To debug a piece of software, you can employ a variety of strategies, including unit testing, code reviews, and pair programming. Before releasing a software program, the job of a web developer is to ensure that the software program is bug-free.

However, bugs can appear after the software is officially released, even after glaring bugs are fixed. This is because it is almost impossible to identify all errors in a product at once.

But all of these plugins are unlikely to give you the desired results. Many of these plugins can trigger code conflicts that can cripple your WordPress site.

WordPress has a debug mode that allows you to pre-detect this type of code conflict. This allows you to resolve these issues before your website goes live. As a result, less time and effort is required to fix emerging website errors after the website goes live.

Query Monitor

Query Monitor comes with some exciting WordPress debugging features. It has a developer tools panel for WordPress. It lets you troubleshoot or debug database queries, PHP errors, block editor blocks, hooks and actions, languages ​​and translations, rewrite rules, queued scripts and stylesheets, HTTP API calls, and more.

It also includes advanced features such as debugging Ajax calls, REST API calls and user capability checks. The notable feature of this plugin is its ability to narrow its output by plugins and themes, allowing you to decipher low-level plugins and themes.

Query Monitor is also known for displaying handy information. After selecting a menu item, you can add an admin toolbar menu to display an overview of the current page and to display debug information in the panel.

Debug Bar

Debug Bar is a highly trusted debugging WordPress tool that you can use from WP admin. It gives you quick access to different types of debugging information such as caches, queries, etc. The tool appears at the top of the site’s admin bar and enables you to debug information from both the front-end and back-end.

In the Debug Bar plugin, you will have several options to identify problems in your code. For example, you can enable tracking of PHP warnings and notifications by activating WP_DEBUG. Also, to find out your site’s performance issues, you can enable SAVEQUERIES, which exposes and tracks MYSQL.

Activate WP_DEBUG

The easiest way to log any issues in WordPress is to activate WP_DEBUG, which you can do by editing the wp-config.php file. WP_DEBUG is the default debug mode built into WordPress and it has 2 subtypes.

One is WP_DEBUG_DISPLAY, which displays errors on the screen, and the other is WP_DEBUG_LOG, which saves error messages in wp-content/debug.log.

To activate WP_DEBUG, you can navigate to the root of your website. You can do this through your hosting provider’s file manager or using a File Transfer Protocol (FTP) client like FileZilla. The wp-config.php file will be located under the public_html folder.
