Howdy Scot,
That’s a good question. I would not be surprised if you are correct, there is a JS conflict between one of your plugins and your theme. Based on the errors in the browser console perhaps it is the events calendar category colors? Relevant error:
?f=wp-content/plugins/the-events-calendar-category-colors/resources/legend-superpowers.js,wp-conten…:16 Uncaught TypeError: undefined is not a function
To help isolate this problem, with the goal of gathering enough knowledge to hopefulyl craft a solution, we should do a conflict test. You might first of all skip the part about switching themes, and see if this issue continue to appear with just your current theme and The Events Calendar plugin enabled. Make sure to disable the category plugin though, and any other plugins not from Modern Tribe. If it’s resolved, then move on to finding which plugin is the problem that way we can hopefully narrow it down to a few scripts.
Please let me know if you have any questions along the way. If not, what was the result of that test? Cheers!
