FAQ
-
Does Safe Mode affect visitors?
-
No. The Safe Mode loader only filters active plugins for admin requests tied to your Safe Mode cookie. Public visitors keep the normal plugin stack.
-
Does this plugin call any external API?
-
No. All analysis is performed locally with native WordPress and PHP functions.
-
Can it permanently deactivate a plugin?
-
Yes. The Conflict Detector includes a button that uses WordPress core
deactivate_plugins()after confirmation. -
How does the AI Debug Helper work?
-
It is a local rules engine. It matches common WordPress and PHP error text with pattern checks and returns a probable cause and suggested fix.
