[Plugin: Diamond MultiSite] links to https

Hmh … the “Diamond MultiSite Recent Comments Widget” all of a sudden links to https? I do not have https configured and an “old” certificate.

Check it at the bottom right widget. Weird enough the bottom left, “Recent Posts Widget” works just fine …

Any idea what may cause this?
