Connecting to my database with dreamweaver

#1

at first i was getting this error:

HTTP Error Code 404 File Not Found.
1)There is no testing server running on the server machine.
2)The testing server specified for this site does not map to the http://domain.com/
_mmServerScripts/MMHTTPDB.php URL. Verify that the URL Prefix maps to the root of the
site.

but i found the solution here in the forums by using servername.dreamhost.com because I host multiple sites.

now I am getting this error:

An unidentified error has occurred.

any solutions?
