Recently, I have few WordPress websites run into White Screen of Death (WSOD) without doing anything by either client or me. The error message can only be observed once WordPress is set to Debug mode. (Change WP_DEBUG to True in wp-config.php).
Fatal error: Call-time pass-by-reference has been removed in /path-to-file/filename.php on line #.
If you found yourself spending too much time watching the loading icon on your WordPress website, it is time to consider a performance optimization. WordPress loves memory! Insufficient memory can lead to slow response, and in the worst case (I’ve seen quite few), WSOD – the White Screen of Death.
If you are a WordPress developer, chances are, you will get this annoying problem from time to time. Don’t be panic, there are ways to get you out of trouble. You just need to know the root of the problem, then apply the solution. Here are few tricks to help you quickly locate the problem.
