Not sure what version of WP i'm using, it's a few back (2 yrs old?) as my dashboard is currently paralzyed. I downloaded, installed and activated Disable Comments, and instantly my whole administration panel ceased to work. Whether i click on Dashboard, Pages, Posts, Comments, Appearance, Tools, Plugins, or any other section or subsection, i only see one thing, a fatal error message that says:
Fatal error: Call to undefined function get_current_screen() in /var/www/vhosts/mywebsitename.com/httpdocs/wp-content/plugins/disable-comments/disable-comments.php on line 114
How do I go about fixing this?
