I think i've screwed it up.... unrecoverable error
 

"We're sorry, but the system experienced an unrecoverable error. Please try again later."


I was checking I had done all the database upgrades as I could not for the life of me get my integration to work.


Is this error a permenant one? B=0

Did you change your database settings or table prefix in the config?

Basically it means if can not find your tables so most likely culprit is incorrect table prefix set in the config-inc.php file

I didn't change my database settings or anything in the config.

Now i've got this error up:

Warning: mysql_connect(): Access denied for user: 'fordmond_gallery@localhost' (Using password: YES) in /home/fordmond/public_html/gallery/pp-inc.php on line 136
I cannot connect to the PhotoPost database. []

I would suggest you make sure absolutely all the new files are uploaded and go from there.

There can only be two things wrong here. You have incorrect database settings in your config file or if integrating with vbulletin 3.5 you have old files most notably pp-inc.php on your server
