WP_Debug is a constant that when enabled will display any PHP errors on the front-end of your site, this is the most useful tool when troubleshooting your site for errors. If disabled and your site has an error you may see a blank screen or content missing on the site but no error message, that makes it nearly impossible to figure out the problem.

Below are the steps required to 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 a text editor (Notepad++ or Sublime Text)
  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. */"

 

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
