it seems that i have the same error, but not with the paypal module.

after installing the shipping module mzmt i get this error:

Code:

if i wait some minutes everything works fine until i click on a link.

When i remove the shipping module everything works fine.

i am using ver 1.3.7

I have no idea on how i change the cache settings in zencart admin.
Can someone please help me with this?
