Welcome to the Q&A Forum

Hey Luca Weird, a similar issue just happened to a friend's site here locally. To clarify, http pages are still indexed if you search - site:https://www.register.it/ -inurl:https  -- but it's just that both http AND https are indexed now. Also - I don't see we.register.it loading at all - only www.register.it --- was this recently changed? Although I am seeing both we and www indexed in Google. Did we always redirect to www? Since the HTTPS is redirecting now to HTTP Google will not be able to see the canonical. Here's what I think you should try; Undo the 301 redirect from https to http In your HTTPS robots.txt file, block crawling Register HTTPS in webmaster tools (if not already) and do a URL removal on all the pages you don't want indexed from HTTPS (probably all of them) I would strongly recommend sorting out your internal linking using absolute URL paths and ONLY link to pages with HTTPS when they actually are really HTTPS pages. Otherwise links to HTTP. Sort out your we vs. www subdomain issue. This is honestly a slightly involved situation, where we can give cursory advice here, but just want to be transparent that if you're not completely comfortable in what to do, you might want to find someone who can peek behind the curtain (unfortunately as Moz Associates we're not able to log into your accounts or anything). EDIT: just want to add that you should be sure you have updated and working XML sitemaps for the http and subdomain you want indexed, and they are submitted to WMT
