For the last two weeks I have tried to log on to the Library page, without success.

This is what comes up;

Server not found

Firefox can't find the server at www.lansingheritage.org.

Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.


What's going on? All I get is a 404 message.
