Multishop - Payment not working

[quickmick1983]

Hello dear Community and Developers

I have a Multishop, runs on Prestashop 1.7.6.3.

As soon as I create a new multi-shop / sub-shop, the payment modules do not work in the new sub-shop.

Previous solution:
I then have to reset them and then re-enter them completely. Both for the main shop and for all sub-shops.
Of course, this is not feasible with planned 100+ subshops.

Is there a solution? Has anyone else had any experience with it?

Thanks a lot!
