Wordpress LScache Plugin: Errors in debug.log
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, would you be able to pinpoint what causes the errors below, from the debug.log? We are just troubleshooting a site that is really slow (backend), not quite sure of the cause, and while doing so, ran into these error messages. Thanks already!
