Howdy WiseSound,
I’m sorry that it disappeared. It sounds like you might have hit a bug a few other people did. In which case you have two fairly easy remedies, just whichever works best for you:
- If you made a backup before updating as WordPress recommends, just revert then update again. It should work this time as we have a slightly newer version out.
- Or, delete the plugin and reinstall it. Deleting the plugin doesn’t remove data so you shouldn’t need to worry about that, but of course as always WordPress recommends backing things up before changes like this just to be doubly safe.
If you need further help would you mind logging in so I can verify your support access? Or, if you don’t have/want a license (which includes a year of support) you should checkout the volunteer community on WordPress.org: The Events Calendar. It’s not the same level of support, but it’s free! We even check those forums once each week and help to the extent we can.
Cheers!
