i been using sagepay and the ceon paid version of the sagepay / protx modual now for 2 years without anyproblem... but latly i have found a really anoying error which as came about on its own.

The problem is as follows:

Normally: when I add a product to my cart then go to checkout and enter my credit card details to goes onto the payment screen takens the money and cames back with a confirmation screen. This works fine and i am making sales.

How ever normally if I enter an incorrect credit card details I get an error message saying please try again... this has stopped... if I enter an incorrect credit card I just get a blank page! this is loosing me customers.

Whats going on?? this error is on both my sites.
