I'm using Wordpress version 4.8.4. In a while, I've experienced some issues in the plugin management panel: I can't manage them at all, no enable/disable, it's impossible to remove or install them.
I can only view a plugin that I've installed named "Admin renamer extended". I've tried updating active_plugins field in wp_options to '', and it didn't work. I've also tried to rename that plugin folder, and if I do that, I can't see the plugin field on admin panel at all.
What can be wrong? Is there any way to fix this?
