It looks though this new Wordpress goody may be interfering with the Broken Link Checker plugin.

This plugin has been among my "must have" plugins for years now. However, since Wordpress was updated to v4.6, my websites are now experiencing major issues.

Two of my websites posts and pages were showing EVERY external link as being broken for several days before this checker even reported them as broken ... even though NONE are broken. I had to Deactivate the plugin on those sites.

The plugin is designed to test all links on a regular bases and if ANY broken links are found, an email is sent to the website's administrator ... which has made it easy for me to keep a closer watch on ALL websites that I tend.

The Broken Link Checker would be a perfect plugin to have merge into the Wordpress platform. That way, we'd all have a constant watch on our links, not just simply at the time of posting or publishing.
