Hi,
I updated WordPress site to the latest version and suddenly the WRI widget I’m using has been replaced by this error:
Fatal error: Cannot use object of type WP_Error as array in /home/***/public_html/wp-includes/class-wp-list-util.php on line 152
The weird thing is that I have a copy of the whole website in a Staging environment in order to test updates in advance and everything went fine. I need this to work in my real site though!
Please help!
