My problem is that when i check the third party mode and save the changes it does not hold, when i try to access some of these third party modes i get this message:
"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."

When i check the permission again i find out that the mod that i wanted to access is unchecked and every thing else is still checked. Any ideas?

my zen cart is 1.3.7
