If you get logged out after one or two minutes this has probably one of following reasons:
Your browser doesn't accept cookies or only from the original webpage. You can change that in your browser settings.
To solve the problem set a checkmark in front of "activate cookies" and no checkmark in front of "only from the original webpage" in the settings of your browser.
If you are using the Norton Personal Firewall (NPF) or Norton Internet Security (NIS): Disable ad-blocking, customize your security settings and restart PC.
Alternatively you can contact the gayProfis-Support or Webmaster whenever you want.
