Weird problem...
Among all the following 6 settings, the first one, general settings, does not work properly. When I did change and press "save change", the page refreshed and nothing has changed. And there is no "saved changes" message. ....All others settings work perfectly. What's wrong?
6 settings:
General Settings
Add/Edit/Delete Items
Category Management
Members' Inventory
Restock Items
Membergroup Functions
