After I deactivate the plugin “referers”, many bug arise.
1.In main menu dashboard, there is many “widget not found”, and the content in it is very strange.[attachment=93:0.png]
2.Many plugin(nearly all the plugin) can not work. They are always show “loading…” or redirect to mainmenu “dashboard”.
If it is not allowed to deactivate it, I think it is better to remove it from settings->plugins, and let it always actived.
