XAMPP has been working for a long while now, but every once in a while I will get this error while trying to start apache, and it won't work:

Only one usage of each socket addres (protocol/network address/port) is normally permitted. : make_sock : could not bind to address 0.0.0.0:80 No listening sockets available, shutting down
una le to open logs

What does this mean?

apache uses (without ssl) port 80. maybe there is an other webserver running, an other programm that uses this port, or your firewall is blocking the port ...

I didn't have any other programs running when I tried it just now, and I would think it would not be a firewall/anti-virus program because it usually works, just every once in a while it will display this error.

You'll sometimes get this message if you are running a P2P program, such as kazaa, when you try to start apache.

something else is using port 80 on your computer there are other posts here about the same problem. search for your error and i bet you will find what you are looking for.
