So, I just updated from 1.2.1 to 1.3.1. Overwrote all the files with the new ones, except upload, public/files, and config. Then, when I went to my <pathtoopengoo>/public/upgrade directory, it doesn't let me 'upgrade.' It says I'm already upgraded to the newest version. If I go to the root directory, I get a PHP error... presumably because I haven't run the update script.
Help, anyone?
