RSVP page not displaying correctly

Hello,

I just installed RSVP ME 1.9.8 with WordPress 3.9.1, and for some reason the RSVP page that users see isn’t being displayed properly. The event description text isn’t displayed, the location and time information goes off the left side of the page, and text such as “#if showMaybeResponse maybe_response
/if#if showDeclineResponse decline_response
/if” is displayed on the page.

I’m not sure if the problem is between the plugin and this version of WordPress (3.9.1), or the plugin and some other part/settings of the site.

Thanks for any information that might help to troubleshoot this issue.

Best,
Chris
