I am so new to this trouble shooting. I am trying to log into my website admin and get this message. It appeared after I I tried to update my plug ins. Now I can’t get into my site admin…this is my livelihood !! Help.
The website is up and running fine. Just no admin access.
Here is the message:
Fatal error: Call to undefined function is_network_admin() in D:\Hosting\6328448\html\wp-admin\includes\menu.php on line 10
