Hi Folks,
Sorry for not keeping you informed and not letting you to test the iFrame One Step Checkout for X-Payments in advance. The last couple of weeks were really loaded with various tasks and things to do - we were preparing two releases - X-Cart v4.5.2 and X-Payments v1.0.5
A couple of days ago we released X-Payments v1.0.5 that is ready for iframe one step checkout in X-Cart v4.5.2. Those who have an X-Payments license can download 1.0.5 in "File Area" section of your HelpDesk accounts.
iFrame one step checkout for X-Payments works in X-Cart 4.5.2 integrated with X-Payments v1.0.5. The most of changes were submitted into built-in X-Payments connector module of X-Cart 4.5.2, but X-Payments needs to be upgraded to v1.0.5, too.
We are releasing v4.5.2 during next couple of days and going to post a joint announcement about v4.5.2 and v1.0.5 once release is done.
For those who use old versions of X-Cart - you will need either to upgrade your X-Cart to 4.5.2 or request/do custom coding of iFrame One Step checkout for your X-Cart version.
X-Payments upgrade is very easy - see
http://help.x-cart.com/index.php?title=X-Payments:Upgrading - you should be able to do it yourself, but backup and using a test environment before going live is highly recommended as usual.
