I have a prestashop redirection problem.

When a new user finish the register steps in my website and click Register, it cannot redirect to anywhere, the address field show the below link and the page is blank, normally it should redirect back to my account. How can I fix this

Blank page = errors

 

Enable error reporting, then try registering again, you'll have more info about what's going on
