WordPress "can't open file"
One of my wordpress installs' wp-admin is completely inaccessible. The site is up and is fully functional for external users. I can see and access the login page. However, when I login, my wp-admin/index.php says "can't open file." When I access the front-facing site, the wordpress bar at the top is visible, but every link from it gives me the same blank page "can't open file."
I searched wordpress support and most posts say it's a database issue. I've checked the MySQL database and it reports OK in both the MySQL cPanel and in the MyPHPAdmin.
I am not having this issue with other wordpress installs on my domain.
I found a folder called "WordPress Support" folder in my plugins that I never installed. Also the last modifed date was yesterday so I knew something was up.
I renamed the folder and files and boom it fixed it. I can now get into my admin page.
Hope that helps
