Hello tpylant,
Thanks on upgrading! Once we get this sorted out I’m sure you’ll love it. 😀
Sorry you’re experiencing this right from the start! A few things could be at play here.
First, it might be helpful to check out our primers. They’re quick videos that will bring you up to speed quickly. Especially this recurring events video; it might have the answers you’re looking for.
Other than that, could I get some more details? It will help if I can reproduce the problem from this end.
It would help to get some more info too. Could I get the answer to these questions?
– Do you have a public link I can link I can look at?
– In the WP-Admin, at the bottom of the Events > Settings > Help tab, there will be a ‘systems settings’ box. Can you copy that and paste it into a private reply?
– Make sure both plugins are activated, as pictured below. Are you using latest versions, The Events Calendar 3.5.1 and The Events Calendar Pro 3.5.2? Since you just upgraded I’m assuming you are, but it is worth checking.

The recurring events feature is located in the date/time box of the event, if that helps at all.

Does this make sense? I’m sure we can get you up and running soon!
Cheers!
– Casey Driscoll
