If you’re having trouble with your WordPress website, you may want to use a debugging tool like wpdebug. A debugging tool can be incredibly useful and can help you determine the problems with your website before you push any code live. This plugin will give you the information you need to troubleshoot performance issues and identify any issues with your theme and plugins. To use wpdebug, you should first download the official documentation for WordPress.
Using WordPress’ debug tool can enable debug mode and display error messages on the front end. Unfortunately, the tool does not allow you to control what messages display on the site, or whether they should be displayed on live pages. Rather, you should use a plugin to turn on WordPress’ debug mode. We’ll cover how to do that in a bit. But first, you’ll need to install the plugin.
WP_DEBUG_DISPLAY is another way to log errors. You can either disable WP_DEBUG_LOG or make it show all errors. If you’re running a development site, turning on WP_DEBUG_LOG is a no-brainer. Even if you don’t want your site to be seen by the public, your website should have some sort of error log.
