an error message saying that the testing server doesn't map to the URL for _mmServerScripts/MMHTTPDB

I see this has been discussed on a few threads, but I'm still stuck.

I'm walking through the tutorial: Building your first Dynamic Website. I'm on part 2, where I'm trying to connect to the test DB.

My local site folder is: C:\xampp\htdocs\check_php\

MySQL is running as well as the Apache server. DB created correctly, with the two tables also from the zip file provided for the tutorial.

Under site setup|advanced Settings my Web URL is: http://localhost/

(I can use the http://localhost/phpmyadmin site through my browser to check the DB files, query, etc. So this looks good.)

The C:\xampp\htdocs\check_php\_mmServerScripts folder is present with the MMHTTPDB.php file present also.

One thing I notice is that the _mmServerScripts folder does not show up in my Local Files folder - even after refreshing. (The underscore must hide this folder?)

When I change the drop-down from Local View to Testing Server I don't see the _mmServerScripts folder, and all folders are red.

I'm on this page: http://www.adobe.com/devnet/dreamweaver/articles/first_dynamic_site_pt2.html under the section "Create a MySQL Connection".

I've changed URL and reentered the connection info multiple times to try to get this to work.

Thanks in advance, sorry for the Newbie question!
