We’ve been using The Events Calendar Pro for years now, and recently noticed a strange bug on our main calendar page:
The calendar initially appears as intended, with our chosen view and custom styles. But upon changing the month, the calendar switches to an entirely different theme/view—see screenshot below.
This is only fixed by refreshing the page, so we gather it has something to do with the calendar’s AJAX loading not playing well with Pro. (Unfortunately, per the developer it’s not possible to disable AJAX on the calendar.)
Both the developer and I have done typical troubleshooting—deactivating all plugins, clearing cache, excluding plugin assets from caching, etc. but the only thing that has fixed the issue is switching to the Twenty Twenty One theme, which is why we believe there’s some kind of conflict with Pro.
I understand there’s a limited amount of support you can provide related to third-party plugins, but just wanted to check in case you’re aware of a solution (my searches didn’t turn up anything about this specific issue). I’ll post dev site credentials in a secure note—thanks!
