Broken Link Error Associated With Embedded Google Calendar

[westrajc]

I've recently added an embedded Google Calendar to my site.  The web page is [ External links are visible to forum administrators only ].  This page is reported as having a broken link, despite it working correctly.  Is there something under the covers that is broken or is this an anomalous error?

[ External links are visible to logged in users only ]
