We have just rolled out Hotfix 1 for Sitefinity 5.0 SP1.
This hotfix release fixes an issue arising in the Ecommerce module check out process when using invalid payment details. The issue is introduced in Sitefinity 5.0 SP1. If you do not have the Ecommerce module or you are not running an Ecommerce web site on version 5.0 SP1, you are not required to install this hotfix.
The fix can be installed by following the standard upgrade procedures.
