This error points to a problem in the Dreamweaver site Definition Testing Server settings.
Going by the error, the URL Prefix on the testing server tab is set to:
www.roseshuttleandsedan.com/
This will only work if Access is set to FTP and an FTP connection can be made.
when you test a database connection, it tries to connect to the testing server and create:
_mmServerScripts/MMHTTPDB.php
Then browse to that file.
My guess is that on the testing server tab, you set Access to Local Network and are using a local path such as c:\inetpub\wwwroot\mySecurityAssistSite
in which case the URL Prefix would need to be:
mySecurityAssistSite
If you want to use the remote server for testing, you need to use the FTP Access method and make sure that an FTP connection is made before testing the database.
