I had exactly the same problem. I checked folder permissions via ftp client, database keys at modules tables and inserted in tables values... Nothing helped.
This solution works: https://www.prestashop.com/forums/topic/275511-solved-you-dont-have-access-to-configure-this-module/
It's enough to click "configrue" on module after sign in to back office on another administrator account. Just this! I don't know why but this workaround works.
I found this topic while I was searching any solution - that's why I write this solution here, for next who will search
