I successfully installed Zen Cart on my shared hosting site with HostMySite. Yay! I could access my store using www.mysite.com/shop, and I got to the admin panel by going to www.mysite.com/shop/admin and logged in successfully.

So then I followed the recommendations here for tightening up security:
http://www.zen-cart.com/wiki/index.p...ecommendations

I edited the admin/includes/configure.php file, changed "admin" to "myNewNAME" in the three places they said. Absoultely no typos, I'm positive. Verified that the changes were indeed in the configure.php file up on the server.

Renamed the admin folder to "myNewNAME".

Went to www.mysite.com/shop/myNewNAME ...
I get the Hello... screen telling me I've reached that screen because either I haven't installed Zen Cart yet or there's an error in the config.

I put the original configure.php file back up on the server and name my directory back to "admin". I still have the same problem.

I AM able to access my storefront.

How do I recover from this?
