Hey there. I'm using the latest My Calendar version (1.9.8), and up until now it has been functioning very well.
Unfortunately, a problem has come up very suddenly that I don't know how to fix: every page that the [my_calendar] shortcode is included on breaks. The title will display, but everything after that disappears. As far as I can tell, the main content div is opened, but the page doesn't display anything after that, including the text that was written above the calendar shortcode.
I've created a sample page to show this problem here: http://eaglefustar.com/ef/schedule/
Any help would be greatly appreciated. Thanks!
