Can't See Male Pics from Potrait Gallery
Unfortunately I don't think the source of the problem is my computer still accessing cache memory. The problem persists on different computers (desktop, laptop, pad, mobile) and at different IP addresses. Plus on my desktop I have upgraded to Windows 10 in the time since this started - and there was no change, I still couldn't see male pics.
I doublechecked and cleared cookies & history again on desktop to no new result.
That's why I wondered if location (in Russia) might result in linkage to wrong server in chain or something like bigbadron suggested. Why the problem just started some two months ago and has persisted since then, I don't have the foggiest.
Anyway - if there isn't anything anyone can do - at least you are now aware the problem exists for some, I'm sure I can't be the only one thus affected.
