Hi there – I recently updated the WP (5.5.3) and PHP (7.4) versions for a site I help manage and it now has blank pages (but header and footer are displaying fine), no access to media library, and is displaying the following in dashboard:
Deprecated: Function create_function() is deprecated in /home/vgzbng16t3tq/public_html/wp-content/themes/squash/framework/option-tree/includes/ot-functions-admin.php on line 69
Notice: Trying to access array offset on value of type bool in /home/vgzbng16t3tq/public_html/wp-content/themes/squash/framework/option-tree/includes/ot-settings-api.php on line 402
Notice: Trying to access array offset on value of type bool in /home/vgzbng16t3tq/public_html/wp-content/themes/squash/framework/option-tree/includes/ot-settings-api.php on line 403
All of these issues go away when I switch themes. I’ve tried troubleshooting in many different ways but no luck. Are you able to help figure out what the issue might be? I will reply with another post for the site info and a temp login.
