Your Internet settings in Windows are conflicting with the correct output of the login window.

Windows 7

2. Click Control Panel.
3. Click Network and Security.
4. Click Internet Options.
5. On the Advanced tab, check the box for Enable DOM Storage.

Cause 2

A tool or setting on your computer blocks Citavi from accessing the Internet.

Solution 2

Check if you have set the (university/company) network as public network on your computer and if the Windows firewall is set to allow Citavi to connect to the Internet from your private networks but not from a public network.

Also check your firewall settings and make sure Citavi is allowed to connect, see manual.

If this does not help, check and deactivate all tools that change or block Internet access (firewall, external antivirus programs, VPN, proxy).

Furthermore, several users have experienced that some routers have problems logging into Citavi 6 after a firmware update. If a reboot of the router does not help, a replacement may be necessary.

If this doesn't help, please follow these steps:
