Yeah, looks like internet explorer has a second use as well (in case you didn’t know its main purpose is downloading a proper web browser application)
describing the problem:
I never log out, but this time I was logged out
When clicking on login/register, nothing happens
Try to disable addons one by one, to see which one causes your problem. Could be adblock? I use firefox, used to have chrome but there was bug with silverlight video, so I replaced.
I think I’ve got closer to the solution.
After activating the “remember me” checkbox, the same error occured with the internet explorer.
Deleting all cookies and stuff fixed it, so I can log in with internet explorer, but still not chrome (deleted the cookies as well).
I’m only using ad block plus and the default plugins like google spreadsheet. Disabling them didn’t solve the problem 
Anyway, thanks for trying to help!
Hmm, thats weird. Just installed chrome 59.0.3071.86 and didnt have any problem with forum. Do you have beta version? Is your antivirus or 3rd party password manager tool somehow implemented to browser?
EDIT: You could try forum with chrome in safe mode. It should rule out or point to 3rd party softwares.
I don’t use an antivirus constantly scanning my computer, I have a firewall active and scan my PC for malwares each week.
I can’t check the version in my office right now, but I can use the forums without any problems home on version 58.0.3029.110 (64-bit) - currently updating, will report again if it is done
EDIT: updated to 59.0.3071.86 and I still have no problems home. I wonder why I have to check for newer versions manually…
This is getting weird.
Came back to my office, and I have the same problem. Updating chrome didn’t fix it.
