The only software i know that supports frontend recurring events out of the box is superevents.
Also no solution after hugh talks with the support team by more than a handfull of ohana customers.
So in the end i wasted time for waiting for the feature, talking to the staff and money for the supscription during waiting.
recurring events are there but not via the frontend (and there is nowhere on our public site that says other ways).
Thank you for your feedback.
