Upgrade problem from version 2.5 to 3.2
I've just upgraded to the latest version however I have run into a few problems. The installation appeared to go ok however minus a style sheet, the page is orange and the page does not have a style. I entered the admin panel ok so proceeded to change the config file. I entered my website path settings and then saved the file but recieved the following error after saving: 'We're sorry, but the system experienced an unrecoverable error. Please try again later'.
I have no idea what I did or how to correct the error. I now cannot access the admin panel to correct the settings.
Any help would be appreciated.
