White Screen of Death

The post explains what the White Screen of Death (WSOD) in WordPress is and why it occurs: usually a script exhausts PHP memory, but it can also be due to a poorly coded plugin or theme or a hosting issue. It notes that sometimes it only affects a part of the site (the admin area or a single post) and that since WordPress 5.2 there is a recovery mode that detects and allows deactivating the conflicting plugin via a link in the administrator email.

It offers a step-by-step guide to solve the problem: increase the PHP memory limit; deactivate all plugins (for example by renaming the plugins folder via FTP) and reactivate them one by one; switch to a default theme; enable WP_DEBUG and WP_DEBUG_LOG to get details in wp-content/debug.log; clear caches; and a trick for very long posts adjusting PCRE limits. It recommends always making a backup before trying changes.
