400 Bad Request

**Coffinwear** · 13 Dec 2009, 05:59 PM

I'm trying to setup my shipping and when I tested checking out with PayPal I got this error:

Bad Request

Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

Any ideas what I've done wrong?

Ok I figured it out. It was too easy.

Remember, always start with the easiest possibilities and it may keep you from getting a headache.

The fix: Clear your cache. That's it.

Thanks for the update on the solution that got things working for you ...

Sometimes a simple clean the cache and/or cookies can go a long way ...

T-H-A-N-K Y-O-U, Coffinwear! I was trying to test my store using the PayPal Sandbox and kept getting a Bad Request page with the message "Size of a request header field exceeds server limit" every time I confirmed an order.

Clearing the cache worked like a charm. You have helped me avoid a long night of frustration. Cheers!
