angsty

Well, I hate knowing someone else has faced this frustration! I hope you have more success than I, but here’s where I’m at if it helps:

I didn’t find a (direct) conflict with a plugin after testing all of them.

I rebuilt my user roles in case there was something wrong there– no luck.

I disabled, deleted and then re-installed WP Fullcalendar in case something was weird there– no luck.

I ran my custom functions.php & includes through a PHP syntax checker — nothing there.

Finally, I disabled a number of permissions-related functions, one by one, to see if one of them was producing the problem and it seems that it was. I had a function that added a line of CSS for non-admin users that hides the discussion options on a custom post type. This was it:

if (!is_super_admin()) {
	function hide_discussion_options() {
	echo '<style>#commentstatusdiv{ display:none;} #commentsdiv{display:none;}</style>';
	}
	hide_discussion_options();
	}

I don’t know enough to understand why this function was preventing the events from showing, but I was glad to be able to at least remove it so that the calendar operates normally.

So, I guess my advice at this point is to look and see if you have any custom functions that might be affecting the calendar display.

Good luck!
