I am having problems with my prestashop 126.96.36.199 install. Currently I have 3 shops in 2 groups using multistore. When accessing "modules>payment" page, I keep getting the error:
"You have more than one shop and must select one to configure payment."
However, I am unable to switch between shop contexts. If I disable multistore I can configure the payment settings, but this means I am unable to configure payment for the other 2 shops. Please let me know if you are able to solve such issue, and I can attach more screenshots/info.
