Thanks for the heads up on how the support replies work. That’s helpful to know.
I host 80+ WordPress installs, most of which are single site installs and a few of which are multisite. Of those installs, only a couple or 3 use The Events Calendar. I’m under the impression from WP Engine that all of the errors are coming from the KVNE website.
The 504 errors aren’t just happening for those using the calendar. According to WP Engine, the errors are happening on all of the sites because of the load the Events Calendar scripts are placing on the server. The 504s happen on the front and backend of our websites.
I don’t know the exact volume of events listed, but I would guess that it’s in the hundreds per month.
Thanks for your help!
