Got a little problem, hope someone can help.

Orders don't show in admin.
Also, after a successful checkout, if I return to the shop, I get a timeout error. Return is set to checkout_success.

Specs:
zc 1.3.9h
php 5.2.17
RapidSSL

GCO 1.4.7
htaccess files created
settings: production mode, htaccess auth false, https, send notifications from zen cart false.

The site is using quite a few add ons, but the one I should point out is Super Orders 3.0 - I did edit admin/orders.php, but does it make sense if using super orders?
However, I tried uninstalling SO but orders still didn't show in admin, everything was the same.

I'm open to ANY suggestions. :)
