Insecure
IssueHigh priority
Resources served over http rather than https.
Why it matters
Anything sent over http can be read or changed on the way. Browsers mark such pages "Not secure" and block insecure resources on secure pages.
How to fix it
Serve the site over https, redirect every http address to its https twin, and update the links listed under Links In.
Skitter runs this check on every crawl, and lists each page it finds with the evidence: the header, the tag or the link that gave it away.
