I've tried to upgrade from 1.9.4 to 1.10.1 - according to the system logs, all completed properly and the cleanup script ran. However, the UI feedback shows: "Internal error occurred - Get technical help!"I've tried reinstalling all of files in order to reset the upgrade process, but I am unsure how to do this. Is there a table in the database that has a flag added when an upgrade fails? There are no errors in my PHP error log file.System Details:Apache Version: 2.2PHP Version: 5.4Mysql Version: 5.5
