Hi @andiroo,
I am going to close this thread, as the one below is the one tracking the issue:
https://stacks4all.com/t/ecwid-stacks-issue/
Please update your stacks to the latest version within RW, and restart RW, and replace the Store Stack with a fresh new one. This should take care of the issue even now that it has returned. You just need to configure the stack to display enough products per page.
