Enabling WP_Debug In WordPress

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. Personally I keep WP_Debug enabled on all my sites so if I install a new plugin or update a theme I’ll know right away if there are any errors and be able to contact the developer to fix them or fix them myself.

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 (I prefer 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 It. Pencils down”
define( 'WP_DEBUG', true );
