I am having the same problem. I can't connect to my database. I keep getting the error that there is no testing server running on the server machine and the testing server specified for this site does not map to the http://127.0.0.1/registration_tutorial/_mmServerScripts/MMHTPPDB.php?Type=MySQL&ConnectionString=host=localhost;uid=root;pwd:root;&host=localhost&&Database=&UserName=root&password=root&Timeout=30URL. Verify that the URL prefix maps to the root of the site. MyMMHTTPDB.php and mysql.php are already in my _mmServerScripts folder in my directory site. I also made these 2 files read only. So I have no idea what causing this problem?Can someone please help me? Thank you.
