Thank you for reaching out to us! I hope you’re doing well.
When visiting your site I could see that your stylesheets are not properly loading and it all points to the Autoptimize plugin. This is how I see your site: https://cloudup.com/cXK5wjyrcZX
I’d recommend you to re-check the Autoptimize settings and see if the plugin is not re-minifying already minified assets (JavaScript and CSS).
I tried disabling Autoptimize, and still had the same result.
I recently installed a plugin called WP Disable, so I went through each setting within WP Disable and found the one that was causing the issue. Can you have a look and see if everything looks ok on your end? https://georgian.edu/events/
Your screenshot seems strange because I would have had someone notify me if our pages had all css removed. Your screenshot was from just viewing our page in a browser? Thanks.
