Hi,

I have installed a payment module from Cardsave which works fine apart from a little problem when a payment is declined. The user gets passed back to the checkout_payment page (Step 2 of 3) and there is an error message in the URL, for example

index.php?main_page=checkout_payment&payment_error=cardsave&error=Your+card+coul d+not+be+authorised.+Please+try+again.&zenid=qhv86ldovv36buhehj78eqpqm2
The problem is that this brings up a blank page and I've figured out that if you cut the error message down to 43 characters (or less) it displays fine in the red error box at the top of the page.

I've simulated errors in other payment modules and they have long error messages that get displayed perfectly.

Can anyone suggest some setting that may have gone wrong here?

Thanks,

Nathan
