My thank you page works (/store/thanks.asp), but on a return from a PayPal sale I get a 404 error ???

Here is the URL PayPal is returning:

Any direction is APPRECIATED!

Hi mxzrxp
This seems to be to do with the length of the Query String which are these parameters added to the URL by Google. (PayerID=76BWMLS4226J4&st=Completed&tx=2DC173512U482101T&cc=USD, etc, etc)
If the length of this query string is under 512 chars then you get the thanks page fine. If it's over then you get a 404 error page. Can you let your host know this and tell them you need a minimum of 1024 for PayPal transactions.
