They are excessing their administration url in the style like this:
http:///www.webshopaddress12345.com/....php?cPath=1_9
(this they can still see, a category list but clicking any product here, comes an "denied" path like the link below)
Denied path that comes:
http://www.webshopaddress12345.com/s...ath/denied.php
The Denied Path has a text:
Sorry, your security clearance does not allow you to access this resource.
Please contact your site administrator if you believe this to be incorrect.
Sorry for any inconvenience.
Before installing the IH4 these same normal product update actions worked. The superuser still works but this other administrative user not. This profile has the access permission for the IH4 as well.
