[TYPO3-commerce] Fatal Error after update 0.12.7 to 0.13.12

Hello Ueli,

As we are not working on 4.6 or 4.7 I’m not sure what happened here. But it seams that the abstract class ist not found in child class. Maybe you could just add a require once at the beginning (as in 0.12.x).

> I now saw that first deinstalling the old version and then installing the new one works. So probably something in the old configuration/data is not compatible with the new version of commerce. Is there any way to do that without having to re-enter all products etc. manually?


We did not change anything in the data-structure. You won’t have to enter the data again.

Best regards

Ingo
