I've had the store up for a while, doing my custom template stuff... etc. etc.. and after a few weeks (today), I go into ADMIN> CONFIGURATION> MY STORE> "Enable phpBB linkage?" and hit "false" as nothing was there (probably from when I set up the store): result:

I can access admin, but home is nothing, nada, blank, no error, no html etc.
url:
"nomadgimp.com"

Zen-Cart: 1.3.8a
Linux: Red Hat Linux Kernel 2.4.21
Apache: 1.3
PHP: 5.2.5
MySQL: 5.0.18
Zend: 2.5.7
NO PHPbb installed!

I am really irked by this, I launch next week, and don't really want to reinstall at this stage having done some other admin setup!

Thanks for interest!
