This is apparently OKCupid's way of telling you that you are deleted. Another thing is; try signing in on a different browser. I couldn't sign in for 4 months on Google Chrome and after trying to sign in on Internet Explorer it worked.

i cant log in the site for almost a month i cant receive anything from my email.. what will i do.. i try to send the feedback but got no reply from it.. am i deleted from the site.? why?

They may have deleted you from OkCupid. They hardly ever do it unreasonably, though. If you haven't done anything you're aware of (such as lying about your age, sending offensive messages) sometimes there are some d!*kheads who just flag your profile for no good reason to get you deleted. But as I said, I HIGHLY suggest trying different computers and different browers. Try signing in on OkCupid mobile (the app and by signing in on your regular mobile browser), and if that does not work then try signing in on a computer using Internet Explorer, Google Chrome, Safari etc. AND ALWAYS make sure you delete your cookies and browsing history. To this day I can ONLY sign in to my account if I use Internet Explorer. I had to delete all my cookies and browsing history and everything, and then sign in. From then on I was permanently signed in but only on IE. But if I sign out, I MUST delete all browsing history/cookies/clear cache before being able to sign in again. If none of that works and you have tried absolutely everything (on mobile [app+browser and mix of different browsers on your computer along with clearing your cache+other things) then you most likely were deleted. In which case, make a new account (which i had to do on IE and also clear cache/delete cookies and s!*t as well just to make it work... again) then repeat steps of clearing everything and using IE to sign in. And it SHOULD work. Good luck everyone!
