Scenario #1 : Your site is totally broken

Did you NOT hear about our cool service called

Unzip the file on your computer and then using an FTP program upload just orbisius-theme-fixer.php in wp-content/mu-plugins.

If that mu-plugins folder doesn’t exist create it.
Next, login as you would normally log into WordPress admin.
Then go to Appearance > themes. One of the default WordPress themes should be active (that’s what the theme fix plugin did).
Now, you need to activate the parent theme that you used or any theme are you know worked.

The page will refresh but it will still showing one of the default WordPress themes.

Now you can remove theorbisius-theme-fixer.php file from /wp-content/mu-plugins/


Scenario #2 : Your site is partially broken

Upload the ZIP file that you just downloaded as you normally would with WordPress plugins (Admin > Plugins > Add > Upload).
Then go to Appearance > themes. Activate a theme that worked before.
Deactivate Orbisius Theme Fixer so the selected theme is used.

No direct database changes are made by this plugin.
