Remote database connection error

I have at least 10 sites set up on the same server, using the same settings and one site is giving me the error that the testing server is not mapped to mysite.com/_mmServerScripts/MMHTTPDB.php

I will call the problem site siteX

If I remove the testing server completely I get an unidentified error therefore something is communicating since it knows the difference is I have the remote server set up or not.

I can connect to ftp files just fine.  I can also connect to the database using navicat.

I am testing on the live server NOT local.

I changed the ftp info to another site that IS working just to see it if would connect to the database using another sites FTP and I could succesfully connect siteX's database using the other sites FTP credentials.
