try going into your WP database (via phpmyadmin for example) and find the ‘payment_gateway’ entry in the wp_options table and delete the value for it.

this worked for me, although it happened again after and had to do the same thing again as above, but since then the error hasn’t occurred.

hope this works for you!

i have the exact same problem..

i get this error when i go to Store > Settings > Payment Options > and then selecting a Payment Gateway from the drop down box (any option in the list)

using
– WordPress v3.0.1
– WP e-Commerce Plugin v3.7.7
– Gold Cart for WP e-Commerce v2.8

if there any solution to this? this is a pretty big issue i cannot set up my store with this error
