If you are seeing ADMIN (and I assume it is referencing the COPIED database, not the original one), then you have basically got the site copying process correct.

The fault on the STORE side is most likely to be your includes/configure.php file.

Sometimes, people "transpose" the two configure.php files.

Remember:

admin/includes/configure.php
and
includes/configure.php

... are DIFFERENT FILES and cannot be "swopped" around.

However, the PATH and LOCATION information that is referenced in both files must be identical - the only exception being the EXTRA info in the admin configure.php file.

So my advice would be to PRINT OUT these two files, and see if there are differences in the data that should otherwise be identical.

And also make sure you are using the CORRECT configure.php file in the STORE side of your installation.

As you give no specific detail about what happens when you try to access the store, I can only surmise that the above is applicable.

However, there could be a variety of issues at play. These include corrupted files, incorrect location of folders and files, etc.
