Hi Trey,
Thanks for reaching out to us. I’m sorry to hear about this, I’ll try to get this right as soon as possible!
First let me say we haven’t heard of any performance issues with the general plugin since our last update, so this seems rather strange to me. To have a clear description of your site setup, Can you share your system information with me?
Additionally I see there’s a file failing to load (https://www.tucsonmuseumofart.org/wp-content/plugins/events-calendar-pro/resources/events-mini-ajax.js?ver=1.0), Can you re-install the plugins to make sure this file is not missing -and maybe other too-? Another thing I noticed in your site is that views with ‘limited’ time (week, month, day, individual events) are loading at an ‘acceptable’ speed, while views that just get upcoming events like list view and photo view are the ones getting slower load times. I think that can be due to the long range of dates it’s fetching from August 3 to April 9, have you customized that range of dates or any other parameter from the calendar query? Can you try to limit the amount of events displayed per page from ‘ WP-Admin > Events > Settings’ to 5 and retest?
Sorry for the bunch of follow-up questions, just want to make sure we move fast on this,
Best,
Nico
