Bryan, thanks for sharing your system information with me.
I checked your site and there are 2 errors on the calendar page. I also see that you are using a bit older versions of our plugins, please update them to the latest as they might fix the issues you are having.
If after the update you are still experiencing odd behavior like this, then I would like to ask you to run a test for conflicts. Seeing that you don’t have too many plugins it should be pretty easy and fast. Here’s a guide how you can do the test.
I’ll be waiting for the results!
Cheers,
Andras
