I have been struggling with this exact same problem for weeks now! I even switched web hosts from GoDaddy to WebHost Freaks hoping this would solve the problem. I think it has something to do with the fact that when Dreamweaver creates a connection (from PHP to mySQL- both running on the web hosting server) it creates a special folder (_mmServerScripts) with special code (MMHTTPDB.php) to process the connection and puts it on your server. I have read in other forums that this is messy and unnecessary junk script- that it should be hand coded. However, I'm not sure how to do that... anyway, I can't get past this problem. I thought maybe it was how I was assigning the testing server root folders or remote root folders. The error code says that the testing URL doesn't point to this special Dreamweaver folder (_mmServerScripts). I'm stumped and appreciate any help!!
