No Payments Page

Hi, Can anyone help. I am new to Zencart and have so far set up this mauch at https://www.ethicsboutique.com. I have a problem as I have tried to make a test sales and gets to the customer info page fine, fill in details and send, then get a blank page, no payment options. I have enabled paypal and cheque payment (edited info to correct na,e amd account etc and showing enabled with green buttons), set zones etc so not sure what is wrong. Any suggestions? The page is completely blank, just a blank white page...?
Many thanks,
Jill

Assuming you're using version 1.3.9, check for error log files in your** /cache** folder and post the contents here if you don't understand what they're telling you.

Thank you, was error after I added royal mail add on. Removed and uploaded fresh shipping module file and working now. Thanks.
