Hi,
Sorry for the issues.
There is a bug in the system causing this.
There are three temporary fixes until we can get a release to fix this.
If you uncheck this setting here:
Events > Settings > General Tab > “Recurring event instances”
It will resolve the issue and show events on the home page.
The other option is to disable Events from showing in the main loop:
Events > Settings > General Tab > “Include events in main blog loop”
The third option is to downgrade all Events Calendar Plugins to 3.11 following our manual update guide:
Manual Updates
We have created a ticket to address this in a Maintenance Release and will update you here once that is available.
Let me know if you have any follow up questions.
Thanks
