I'm having a problem and I have checked files, had my server host check and re-check files and have narrowed the problem to be template specific because I tried this situation with another template and could not duplicate the problem.
The problem is when using Fast and Easy checkout AND Zone Rate for shipping, when the customer fills in their name, address etc on the login page then hits the SUBMIT button they get an INTERNAL SERVER ERROR.
If I deactivate FEC all works OK.
If I activate FEC and change to Flat Rate of Free Shipper - all works OK.
I really need FEC and Zone Rate to be working together as I ship world wide, and would like for my customers to be able to check out
"FAST and EASY".
Could you please advise as to how to fix this problem?
Thanks in advance --- Paul.
