This probably doesn’t come up often, but it took awhile to piece this together, so here it is so I can find it again.
If you use the Event Calendar plug-in for WordPress and don’t want the dates to show up in the RSS feed, this post has the answer. Comment out line 570 in eventcalendar3.php, like this:
This will stop it from prepending a plain-text schedule to your text.
The other solution is to comment out this function entirely in lines 594 and 595, but I was having problems with the excerpt showing up for any post in the event category. And I didn’t feel like creating a new template for just that category since this isn’t really an earth-shattering problem.
There are some other broken things too about this function, but haven’t figured those out yet. Boo.
