Enabling WP_Debug In WordPress

WP_Debug is a constant (a permanent global variable) that when enabled will display any PHP errors on the front-end of your site

WP_Debug is the most useful tool when troubleshooting your site for any potential errors or warnings. If disabled and your site has an error you may see a blank white screen or content missing on the site but no error message, that makes it nearly impossible to figure out what the problem exactly is.

Enable WP_Debug Via Plugin

If you are looking for a one-click method or you are not comfortable editing a file using FTP access in general simply use this plugin to turn on WP_DEBUG mode instead.

One-click method to turn on WP_DEBUG mode
  1. Install and activate SO Turn On Debug plugin.

Plugin setup is minimal and requires no knowledge of editing or code, and since there are no settings, upon activation of the plugin, WP_DEBUG is set to TRUE in the wp-config.php file of your site.

Enable WP_Debug Via WordPress

Follow the steps below to enable WP_Debug for your WordPress installation.

Enable WP_Debug for your WordPress installation
  1. Access your website’s root folder via FTP or SFTP.

  2. Locate the wp-config.php file.

  3. Open this file in any text editor.

  4. Search for WP_Debug and if you find it set the value to TRUE if currently set to FALSE.

  5. If you didn’t locate WP_Debug scroll down near the bottom of the file and add the following code right before the line that says That's all, stop editing! Happy blogging publishing.

The true and false values in the example are not set in apostrophes (') because they are boolean values.
