Redirect not working after upgrade

I upgraded my plugin to the latest version yesterday, and my page redirect is no longer working. On this page: http://www.bellingham.org/activities/ if you click “Event Calendar” on the right, it SHOULD redirect to http://calendar.bellingham.org but it’s not working.

Please help! I don’t know if it’s a compatibility issue, or if I need to make changes since upgrading.

Here are the page settings:

ID: 5264
post type: page
active: 1
no follow: 0
new win: 0
type: meta
rewrite: 1
original url: http://www.bellingham.org/activities/event-calendar/
redirect to url: http://calendar.bellingham.org

Thanks.
