Hi Erin,
Thanks so much for reaching out!
I’m sorry to hear that you are experiencing this issue. For now, the best place to post is the WordPress forum, as the premium forums are for paid users. With Events Calendar PRO, you get premium support in a shorter timeframe, with more individualized attention.
If the following month isn’t showing in Month View, I’d recommend running through our testing for conflicts procedure as a first step. If that doesn’t shed light on the issue, try flushing your permalinks by going to Settings < Permalinks and Save Changes. Beyond that, you can get assistance back on the WordPress.org forum.
I hope that helps!
Thanks,
Jaime
