One Page Checkout - blank web site

[kyrre]

Hi guys

I updated from 1.3 to 1.4 (latest), and when I enabeled the OPC the OPC functions did not appear on the checkout page, so I uninstalled the OPC - and now my site and admin is completly blank.

http://pushvideo.no

Please help!

How do I install the module from phpmyadmin?
or
How do I uninstall OPC?

I have cleares the smarty/compile sections (it's a smarty_v2 as well)

Ok, so far no help in sight

I tried to import the backup database, but it could not overwrite the 1.4 changes. Had to make a new database, import the backup, transmit all the files from the backup folder - and now it works. Almost. The modules list is blank, but the most important is that the shop is online. Can't figure out what's wrong in the backend.

Anywhoo... I deleted the 1.4 database with the error, did the same as above in the original database placement, and then I ran the upgrade again. I now got the backend running, but the frontend is still blank. The test URL http://pushvideo.no/abtest/ redirects to http://pushvideo.no/abtest/login.php when I try to acces it.

Any help on that issue? Can't quite find the right keywords to search for...
