Hello. I’m having the same problem, but it does not happen all the time.
When I first visit my page and try to use the upcoming events widget, the problem happens where it starts to show the event, but then just hangs saying “Loading Event Form”. However, if I go to the calendar page or some other page, the widget seems to start working, even if I go back to the home page.
I’ve made the changes you suggested, updating the .js file and the widget_upcoming.php file, but behavior is still the same.
Looking in the console, i keep getting the following messages:
No relay set (used as window.postMessage targetOrigin), cannot send cross-domain message
LOG: [jquery.form] terminating; zero elements found by selector
I’m not really a developer, so I’d appreciate any help you can provide.
