Hi Theresa,
Thanks for reaching out! This was actually a known issue in previous versions of the Events Calendar, but upgrading to the most recent version (4.6.1) should resolve this issue for you. Make sure to clear any caching you have on your site after updating, and disable the “Enable month view cache” option under Events > Settings > Display. Once your events are showing up again, you can re-enable this setting.
If you need further assistance with this, will you please post this question in our Events Calendar PRO forum? We use the Pre-Sales forum to answer questions about the features of our premium plugins for those interested in purchasing them.
If you have not purchased one of our premium plugins, you can post in our community forum on wordpress.org, which we review weekly to check for bug reports. If you need more in-depth support, you will need to purchase a license.
Our knowledgebase is a great place to start looking for answers. You can also search our premium forums to see if another user has posted about a similar issue. If you’re having trouble with plugin functionality, the best place to start is by testing for a conflict.
Thanks,
Jennifer
