BTW: I found a quick work-around while I was waiting – just change the link to page to call the ?action=blablabla&tribeHideRecurrence=1 (in case anyone wants to use this method instead).
Well, this is a little bit more than embarrassing… it appears one of the other admins enabled the hide option for the settings on the network admin dash.
FYI – I’m not using dashes in my date format and I have the exact same problem with recurring events. Setting a fixed number of events works around the problem but my date setting is dd/mm/yyyy
It doesn’t even create the additional events (only the first) unless I provide the number of events to end after (as described above).
