500 - Internal server error

[pukka]

Hello,

I'm having a problem with the orders & paypal gateway modules. It's a brand new site running the latest version of CMSMS 1.11.6 "Merchena". I've also got the latest version of the orders and paypal gateway modules running.

On the backend, clicking order manager or paypal gateway (to navigate to those modules to set them up or anything else) results in the following error message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

On the frontend, if you navigate to a product and click add to cart or click view cart, the 500 internal server error occurs.

If you enable debug however you are then able to navigate to both modules on the backend as well as add items to cart and viewing items in the shopping cart.

Any ideas as to what is going on and how to fix it? System info is included below:

You should provide the apache error log content for the specific browsing timeframe where you got the error.
