@robert681: I updated the PublishPress Authors Pro
plugin and also the WP Activity Log
plugin. Suddenly this issue appeared when I opened the admin page for the “Popups” post type of the Popup Maker
– the page didn’t load completely, the post list entries were missing and the PHP fatal error posted above occurred. But the issue also appeared with other post types, so this is a problem unrelated to Popup Maker
plugin.
Flushing the WordPress cache (transients) didn’t help. Disabling the object cache (WP Redis) didn’t help either.
After disabling all plugins and re-enabling them again (standard debugging procedure),
that issue went away when either the PublishPress Authors Pro
or the WP Activity Log
plugins or both were disabled.
Disabling and re-enabling the WP Activity Log
plugin fixes the issue permanently.
Re-transferring the production database to development “re-poisoned” the site and the error occurred again until the WP Activity Log
plugin was disabled and re-enabled again.
It seems that the WP Activity Log
plugin does something when it is disabled or enabled and cleans up something that isn’t stored/cleaned up as normal WordPress transient.
The issue can be fixed by disabling and re-enabling the WP Activity Log
plugin, but the underlying issue is still there – some kind of cache leak. Therefore I posted the details about this fatal error as it can be helpful to find the underlying issue and fix it.
