Running XenForo 1.3.0 Beta 3 Trying to upgrade to the latest version of 1.3 Uploaded all the upgrade files and chmod 0777 to the data and internal_data, all sub dir and files below that When I go to the site I see an "upgrade in progress" and when I got to the install directory I get an 500 Internal Server Error (copied below) Now the interesting thing, when I do a restore on the files only in forum it starts working again. Any ideas? Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, webmaster@ and inform them of the time the error occurred, and anything you might have done that may have caused the error.
