error in events made for 2014

Is that link you shared came from the default full calendar? since if you noticed at the demo site the link is quite different

eg.
https://demo.wp-events-plugin.com/?ajaxCalendar=1&mo=10&yr=2013&limit=3

I think this is a custom page you created, right? If so, I don’t think we can help you fix this as it’s your customizations that’s having issues rather than our plugin.

If you’re not using customizations, how are you making this page? Does it work in a default WP theme?

Thank you, I solved the problem. I removed all the customizations in the page (wich were made by somebody else) and used the standard shortcodes. Works like a charm. Thanx for helping me finding the problem, and figuring out the solution.
