I've searched through other support requests and found someone else who has the same exact problem as me here: https://premium.wpmudev.org/forums/topic/turn-off-comments-on-events
I've tried to turn off the comments as suggested in that post, as well as using the plugin which can remove comments from custom post types. I have that plugin removing comments specifically from events. Unfortunately none of these steps work.
The other person was able to avoid it in CSS with a display-none-rule, but I'm not that good enough to figure that step out. So I was hoping to get an official fix for this problem.
Here is a test link on my site.
Any suggestions to try?
