Sites such as www.en.wikipedia.org and www.commons.wikimedia.org redirect to their non-www equivalents (en.wikipedia.org, commons.wikimedia.org). However, when accessing these www. sites over HTTPS there is a host mismatch, as wildcard certificates are not valid for multiple levels of subdomain. As such, visiting https://www.en.wikipedia.org throws an invalid certificate error.
Why are you visitng these domains? There isn't any nice way of fixing this, as WMF isn't going to waste money on buying sub-subdomain SSL certs...
(In reply to Sam Reed (reedy) from comment #1) > Why are you visiting these domains? As I understand it, there's a reason that www.commons.wikimedia.org and similar URLs were created: it's convention and standard practice for this type of domain format to function properly. There are older Bugzilla bugs about this, I believe.
