Hi, I have recently enabled SSL on all pages administration and noticed that your logo breaks it when opening the "CDN Sync Tool - Options" page in the administrative dashboard.
The offending line is:
<img src="http://plugin.fubra.vc.catn.com/logo.png?host=http://www.mywebsite.com&plugin=cdn-sync-tool&ver=1.9" alt="CatN" />
Maybe you could consider fixing this?
Cheers,
Stephen
