Hi there, I’m experiencing the exact same problem with the Throne Theme from Meks.
As soon as you enable Calendar Pro add-on the pagination on the home page stops working and redirects to the home page. I see there are other threads on the forum with the same symptoms that have been closed without resolution.
If you aren’t able to offer a solution are you happy for me to provide the Theme developer with your plugin in order that they can see if there is a way around it?
Thanks
