Recurring Events function not working after update

Hello – I’ve checked about 8 pages back of topics and not finding this listed anywhere (but please redirect if I missed it).

We just updated the plugin and now the Recurring events feature does not seem to work. All previously made pages now have the Recurring event either missing or slightly off (by an hour or so) and anytime we try to fix the error or create a new Recurring event, we receive this error message:

“Fatal Error: Call to undefined method Trive_Events)Main::rebuild_known_range90”

Did all usual testing for conflicts and this didn’t come up.
