I'm just now using your plugin and trying to combine it with Google+ Events which seems to be really close to working.
I've found that the plugin will add an extra string of characters "&ctz=" to the end of an Event URL and this will break a link to a Googe + Event.
Example, see July 26th here, the second link titled "Event Testing"
The More Details link will take you here - https://plus.google.com/events/c0phfcar939351o3tski45dbrts&ctz= which you'll get a 404 page in google +.
If you remove "&ctz=" the event works properly https://plus.google.com/events/c0phfcar939351o3tski45dbrts
Any ideas how this string is being added?
