Hello,
I’m sorry that you’re running into this issue, but I’ll be happy to help you figure out what’s going on.
First, can you make sure that you’re running the current version of WordPress (4.9.6), The Events Calendar (4.6.16), and Events Calendar Pro (4.4.26)? Next, please try running through the steps outlined here to check for any conflicts that might be occurring between your theme or other plugins. If you don’t have a testing site already, the free WP Staging plugin will let you create a quick copy of your live site that you can use for testing.
If this doesn’t make a difference, can you share your full system information with me?
Thanks,
Jennifer
