If your site is experiencing issues that you think might be related to PHP issues, here’s how you turn on error reporting in WordPress:
Find line one below in
wp-config.php, comment it out, and add the rest below. This is meant to be done on a development site, in a local environment.
WordPress will now start logging errors in
debug.log file within
Even if you don’t notice major errors with your site you can still often find warnings on deprecated code or other PHP issues.
