Killing my shortcodes

I have this RPwE plugin loading an excerpt on the homepage of a site I’m building, where I also have a shortcode to load a series of upcoming events from the My Calendar plugin.

I installed the events one first, and it works beautifully… until I activate the RPwE widget. Then, instead of a proper parsing/rendering of the calendar’s shortcode, the shortcode itself shows up as text in the browser. The excerpt loads just fine.

If I remove the RPwE widget, all is well with the calendar/shortcode. I have never seen a problem like this before! Help!

Here is the shortcode that’s showing up… I don’t know how this plugin might be interacting with it to deactivate it:

[my_calendar_upcoming before="0" after="4" type="event" template="{image}{shortdesc}{title} {date} • {time}" order="asc" skip="0"]


Any thoughts? Let me know if you need more info to diagnose.
