Suite Errors on forum after upgrade
 

Thankfully, my problems happened on a cloned database of my live forums, so hopefully I'll be able to get some help here and figure things out before I try this for real. Not entirely certain that these errors aren't because of using a cloned database in a different directory though.

What I did was upload the vB4 files to a new directory for testing purposes, using the config.php.new from that package and copying over settings from the live forum, except for database settings which got the stuff from the test forum. Since it was a fresh upload with no vB3.8.4 files, I couldn't login to the admin panel first to shut things off, so I simply went and disabled the addons in the original database through the config.php, then ran the upgrade. Now...I have no idea what's gone wrong. The error codes seem to be pointing to the filecache, but that's not making a lot of sense to me.

I'm getting the following errors at the top of the forum index

If I go to the admin CP, I get something similar.

Any attempt to login gives me a white page with the following error.

I'm not able to login anywhere, or change any settings except through direct modification in the test forum database. I've already made sure that the URL in there is the correct URL for the test forum, and that the forum default skin is the vB4 skin. No dice.

Any suggestions for how I can fix this?
