Ok...first excursion into shopping carts..(using my test site)
created a Mysql db via cPanel......installed Zen-cart 1.2.7...with demo data...ran the installer, which was great and intuitive, with good info (thanks...very nice).
Last page of the set up screen has 2 buttons - one for the store access (www.webhj.com/catalog) which loads OK. I can access the store.
and one button for admin which does not load - 404 error page not found.

I closed down my computer after an hour or two of frustration, and now (next day) I'm asking myself....'where IS the admin page that everyone talks about'
How do I access admin....?? There is no admin access link on the store page, unless 'guests' is another name for admin. Anyway this doesn't work either.
If it is PHPMyadmin...how do I access.?

And the install document does not spell out where admin access actually is.
I'm guessing this first install page (with the links) provides access to the admin, and provides guidelines from there, but since I have never seen them, I do not know where to look.
Basically I have store, but cannot change anything.

I cannot find any references in the forums either......perhaps a reinstall.?

You help would be greatly appreciated.
