I need an urgent help, if possible. I installed a plug in called "feature a page widget" and it didn't work. I deactivated it and even deleted it but now I cannot use the Widgets from the Dashboard anymore,
I receive the following message:
Fatal error: Call to undefined method stdClass::add_help_tab() in /home/punctuld/public_html/wp-content/plugins/feature-a-page-widget/feature-a-page-widget.php on line 108
The plug in is deleted and this message is still there.
Please give me an advice how can I solve this. I have a beginner level therefore please be very explicit.
Thank you very much in advance !
