After a server move I get the following errors anytime I click on ANY post, ANY thread, ANY forum, ANY user:

Invalid Forum specified. If you followed a valid link, please notify the

No Thread specified. If you followed a valid link, please notify the

This user has not registered and therefore does not have a profile to view.

You can load the forum index and see the names of threads, forums, users, the post previews, etc. All of that loads and works perfectly until you try and go deeper. memberslist.php even works correctly, until I click on a member and then I get the "This user has not registered" error.

I cannot login to the forum via /admincp or from the forum index, it is rejecting my password which I know to be correct, and has been verified by other individuals to not be functioning either.

The mysql database was backed up using shell, and imported onto the new server a total of 3 times. I personally and my webhost both have verified that there is data in these tables, and the rows. There are the exact amount of rows in this database as the one on the original server that worked perfectly. I've done a mysql backup using ssh and also by the mysql administration tool. The database is good.

The site is heavily modified. I've disabled hooks in the config file. I'm stuck and cannot figure out what else to do. Please help :)
