My server host sent me an email telling me to upgrade my PHP from 5.2 to 5.4.
When I did this my site got all crazy and I got an error message generated by ZenCart.
I do not have a copy of the error message on hand, but can switch it back to 5.4 to help describe the issue further.
Upon switching back to 5.2, the issue fixed itself.
I searched to find others with the same issue and could not find the same issue - apologies if this has already been addressed.
