Hi, Robert. Sorry you’re experiencing this.
This isn’t currently a known issue so I’d suggest following these recommended troubleshooting steps for your own site:
It looks like you’re using the latest versions of our plugins so please follow our Testing for Conflicts Guide (basically switch to Twenty Seventeen theme and deactivate all plugins and custom code other than Modern Tribe plugins) and see if that helps narrow down the cause of this.
Of course, we always recommend restorable database and file backups before modifying anything on your site.
If it doesn’t, please enable WP_DEBUG and WP_DEBUG_LOG (which will create a file on your server at /wp-content/debug.log if there are any WP_DEBUG messages) and share any debug messages you see while trying to replicate this issue and doing other things on your site relevant to this ticket (such as visiting your site’s home page, events page, single-event pages, and anything else you can think to do).
Then, please share your System Information (while in Testing for Conflicts Mode) in a Private Reply. That will give me a lot of extra information to help troubleshoot this.
You might also see if you can spot any console errors at your site. (If needed, you may reference our KB article Using Google Chrome Developer Tools.)
Let us know what you find out. If you’re not able to determine the conflict here, please share an annotated screenshot or screen capture video to clarify exactly what’s happening here.
Thanks.
