XF 1.4 Error upon upgrading my site


Well-known member

Was upgrading my site today, and the following error seemed to exist when I went to the site:

Fatal error: Class 'XenForo_Autoloader' not found in /home/mycourtt/public_html/index.php on line 7

Then the install page doesn't seem to be accessible appearing as a blank white page.

Ensure all of the files have been uploaded correctly.

If in doubt, download a new upgrade .zip and reupload everything.
