(Below is a copy of what I tried to send to you on the official support page, and then when that didn't work, to support@btcsquare.net via email - if the email worked, then I'm sorry to send this again, but with the official support page not working, I think you can understand me posting all over the place for help, hoping for a reply)

The login page is not working - when I log in, I get redirected to the main page without being logged in. This happened on another PC on another network as well.
Also, I tried making another account, and although the account making was successful, I couldn't log in to that account as well.

So this seems to be some part of your site not working, as opposed to something with my account / my pc / my network being the problem.

I tried contacting you with the support page on your site, but that page wasn't working too.

I hope this email gets to you without any problems, and I hope you fix this big issue quickly, and notify us what's the problem, how long it's going to take to fix this, etc as soon as you find this email / issue.
