Hello,
I just installed prestashop v 1.7.7.1 for a client at a webhoster. I connected his prestashop-addon account to the shop.
When I access the Module -> Module catalogue for the first couple of times, the page tries to load modules from the store (I think), but is only showing the white and empty boxes of modules.
After accessing the page again after some time the following error occurs: "The Controller AdminParentModulesCatalog is missing or invalid".
I checked via FTP and yes, the Controller is missing (Controller -> Admin). I downloaded some previously versions and there is the controller missing too.
Hope you can help me.
Thanks and regards
Christoph
EDIT:
I just found out, that the Module "PrestaShop Marketplace in your Back Office" is required for the catalog. It was deactivated in the shop, I activated it an now it works.
