Im running Teacommerce (2.2.3.b2) on an Umbraco 6.1.6 with Klarna as payment provider. Most of the time it works, but some random orders orderlines are not saved to the Teacommerces database, BUT they are saved to Klarna (visible on Klarnas website). The total sum of the order is correct though (in the database also), but the orderlines sum is on Transaction fee and not Subtotal.

The only errors I find (in App_Data\Logs) is this (Teacommerce backend says this order was finished 2016-01-23 06:14).

Any idea what could be wrong?

What do you suggest I do? Upgrade Teacommerce? If yes, in what order? The licence is only for v2.x.x
