Understanding WordPress Debugging

WordPress is a CMS subject to a great deal of analysis. A few clients guarantee that the stage doesn’t ensure information security. For other people, locales created with this product experience mess with consistently. WordPress is one of the most mind-blowing instruments for making and dealing with a site. In any case, you should know how to utilize it appropriately to avoid the different troubles that might emerge. In web programming, you must be unsurprising and wear a few caps. More is required to have been a designer. What’s more, you really want to know how to investigate when you experience a bug. On account of this article, you will comprehend the WordPress investigation.

What Is WordPress Debugging, And What Is The Point?

Troubleshooting PHP code is a fundamental stage in most web programming projects. Without a doubt, WordPress isn’t the leading CMS in view of the PHP language. Many substance executive frameworks, such as Drupal and Joomla, are created with PHP. Nonetheless, on account of WordPress, explicit troubleshooting components have been incorporated. These instruments intend to work on the WordPress troubleshooting methodology and blend the code at the center, module or subject level. On the off chance that you are experiencing issues with your WordPress site, empowering troubleshooting mode can be valuable. This will permit you to recognize any oddities and will feature specific components, for example,

  • PHP errors
  • Notifications
  • Warnings

Troubleshooting WordPress like this permits the designer to see messages that can assist them with deciding the beginning of an issue on the site. It then becomes more straightforward for him to take care of this issue. The investigate mode is legitimate not just for the software engineer who fostered the site but also for the site proprietor, who isn’t guaranteed to have the profile of a designer. Without a doubt, contingent upon the message that is shown and the mistake that has happened, the site proprietor can illuminate its engineer regarding the expansion or subject that is causing the issue. This data will assist them with amending botches to upgrade the activity of the site.

WordPress Debug Log: What is it?

When you empower WordPress to troubleshoot mode, various messages might show up on the site toward the front or back end. These messages let you know the issues that have happened and, now and again, the lines of code that are the reason. Nonetheless, it should be noted that these messages are not saved to a particular area. Hence, it is essential to keep these messages to assist designers with settling the issue later.

To record these messages, WordPress has given the initiation of the investigation log. The motivation behind this log is to store all notices and mistakes in a record on the site server. When the troubleshooting log is empowered, WordPress records all issues in the wp-content/debug.log document. To license this element, you should set the WP_DEBUG_LOG steady to “valid”. Moreover, it is likewise conceivable to determine a custom registry way (unique in relation to the default catalog) where the wp-content/debug.log record will be put away.

Would you like to log issues in your log without uncovering them freely in the HTML code of your site pages? You can utilize the WP_DEBUG_DISPLAY consistently to do this. On account of this, you will actually want to keep WordPress investigating mode active while staying away from the presentation of mistake messages on the site. As a rule, join WP_DEBUG_DISPLAY with WP_DEBUG_LOG. It’s more helpful, particularly as far as client experience. To be sure, a client can close a website page in the wake of seeing a mistake message somewhere on your webpage. This will adversely affect your regular referring to.

Enabling WordPress Debug Mode

Enabling WordPress debug mode can be done in a variety of ways. In this article, we will mainly look at three activation processes.

  • Activation of debugging mode with a tool offered by the hosting provider;
  • Activation with a debug WordPress plugin;
  • Manually enabling debug mode.

First Method: Enable Debugging With A Tool Offered By The Hosting Provider

Today, many websites have a single-tick WordPress establishment instrument. These suppliers usually offer a clever utility that permits you to empower WordPress troubleshooting mode. With this utility, you won’t have to roll out direct improvements inside your wp-config.php record. It is a commonsense component for straightforwardly and rapidly initiating troubleshooting mode and broadcasting messages on your site.

The issue with this kind of utility is that you will require help dealing with the WordPress investigation log. You can likewise not control the showcase of messages on the pages. In this way, mistake messages can show up anywhere on your site’s pages. Nonetheless, the utilization of the troubleshooting log is fundamental. We recommend that you introduce a WordPress expansion committed to investigating mode. This will make troubleshooting more complete.

This first strategy for troubleshooting WordPress enjoys one benefit. You ought to realize that particular blunders prevent you from getting to the site’s dashboard to search for potential reasons for the issues. At the point when you empower troubleshooting mode through the utility, you will actually want to see the guilty lines of code and the blunder messages returned by the framework all the more effectively.

Method Two: Use A Debug Extension

If your web host does not have a debugging utility, you can use a WordPress plugin to debug your site. You will easily find a qualified, free plugin for this. In the plugin library on WordPress.org, there are several options, but we recommend using WP Debugging from developer Andy Fragen. This extension is free and easy to use. As soon as you install and activate it, it comes into action immediately. By default, the WP Debugging plugin sets the following settings to “True”, which means it enables the following features:

  • WP_DEBUG: this constant turns on debug mode;
  • WP_DEBUG_LOG: this constant store’s messages in a log file;

We will focus further on the exact functions of the last two constants, namely SCRIPT_DEBUG and SAVEQUERIES. In the WordPress administration interface, you can make some settings so that the debugging mode is effective. Go to the “Tools” tab and select “WP Debugging”.

After you finish debugging and make any necessary changes to fix the issue, make sure to turn off the extension. If you do not do this, the debugging mode will always remain active, and your visitors will be able to see error messages on their navigation screens in the event of a problem.

Third method: Manually Activate WordPress Debug Mode

Physically empowering WordPress troubleshooting mode must be finished by altering one of the primary CMS documents at the server level. It would help if you physically embedded the WP_DEBUG and WP_DEBUG_LOG constants into your wp-config.php record. To do this, utilize an FTP client to get to your server and make changes to the referenced record.

Of course, the wp-config.php document is situated in the central catalog of your site (except if you have moved it for security purposes). Troubleshoot mode is enacted in this way, and you can make any changes you wish to settle your site and resolve issues. Toward the end of the investigation, you have two choices. You can either set the constants to “misleading” or eliminate the code bit to debilitate troubleshooting mode.

Other Options For WordPress Debugging

The three WordPress debugging methods we just looked at are the ones developers typically use. Apart from these methods, other options can also help you with debugging. These are precisely integrated or third-party tools. Remember, we said we’ll cover the SCRIPT_DEBUG and SAVEQUERIES features later. These are relatively effective options for performing WordPress debugging. Here are some alternatives to the three methods previously mentioned.


The SCRIPT_DEBUG functionality is a constant that forces WordPress to use development versions of core JavaScript and CSS files. The minified versions usually loaded are then no longer taken into account. This constant can be valuable when committing changes to embedded .js or .css files. To enable SCRIPT_DEBUG, you have the choice between two solutions. You can first use the free WP Debugging extension mentioned previously. This extension enables SCRIPT_DEBUG by default. The second option is to add the following constant to your wp-config.php file:

define( ‘SCRIPT_DEBUG’, true );

SAVEQUERIES: Database Query Debugging

If you encounter problems with your site’s database, you can set up a database query logging procedure. This can be done by activating the SAVEQUERIES constant. Enabling this constant allows you to track:

  • Each query performed on the database;
  • The function that called the database query;
  • The query execution time.

Enabling query logging can be done in two distinct ways. First, you can resort to the WP Debugging extension, which triggers it by default. As we mentioned previously, this extension is free. The second method consists of integrating the following constant into your site’s wp-config.php file:

define( ‘SAVEQUERIES’, true );

Please note that this action is likely to have a considerable impact on the performance of your site. It is, therefore, recommended to use database query debugging on a staging site.

Using the Query Monitor extension

Like WP Debugging, the Query Monitor plugin is free and effective for WordPress debugging. Query Monitor is primarily used to diagnose various aspects of WordPress, including:

  • PHP errors;
  • Database queries;
  • Actions and Hooks;
  • User capabilities;
  • HTTP API calls;
  • Editor blocks;
  • Style sheets and scripts pending, etc.

Query Monitor is definitely one of the best WordPress debugging tools you will find on the market. Many users prefer it to other tools. After installing and activating it, you can access the new features in the WordPress toolbar. A box dedicated exclusively to the extension provides additional information necessary to perform debugging.

New Relic

New Relic is a high-quality tool for analyzing and diagnosing the performance of a website. It can be a valuable ally in detecting possible problems or malfunctions that hinder the effectiveness of your web platform. Your web hosting provider may already have a WordPress debugging tool built into it. However, sometimes it is helpful to use New Relic.

Why Turn Off Debug Mode When You’re Done?

Investigating WordPress is essential to examine issues on a site. In any case, for the sake of security, you totally should keep it enacted 24 hours every day. Without a doubt, you ought to realize that troubleshooting mode can uncover some portion of your PHP code. In any case, not all guests to a site have a similar profile. A few guests are qualified engineers. Others, as well as knowing how to create in PHP, may need better expectations. They can hack your site and cause boundless harm to it. We suggest that you switch off this mode when you are done investigating.


Sites, whether made with WordPress or some other improvement instrument, can encounter glitches. You might have to determine issues on your site. On the off chance that your site was made with WordPress, consider changing to troubleshooting mode prior to settling on any problems. This mode permits you to recognize and determine blunders usually inborn in the PHP language. There are a few strategies for troubleshooting.

With some facilitating suppliers, enacting WordPress troubleshooting mode should be possible straightforwardly utilizing a devoted instrument. Yet, you can likewise use a WordPress module to investigate your site. A third strategy is only suggested when you are an expert engineer. This includes adding code pieces to the site’s wp-config.php record. In the wake of altering in troubleshooting mode, switching off debugging is essential.
