Problem Moving vB5

[grayloon]

I'm trying to move my forums to a new server. I've moved the files and database. When I access my forums, I get an internal server error. The apache error log shows issues with the API calls or something. Can anyone decipher and help me correct this?

PHP Fatal error:  Call to a member function fetch_userinfo_value() on a non-object in /home/domain/forums.domain.com/public_html/core/vb/api/state.php on line 316
