My server's been having a lot of problems in 1.6.4. When I finally figured out what the problem was, I fixed my server. That was a day before 1.7.2 came out. When 1.7.2 came out, I updated my vanilla server to 1.7.2 and still no one, but me (localhost) can get on.
I've - checked my firewall settings, - re-portforwarded, - Tried the .exe AND .jar server files they have on minecraft.net.
What's the problem? and how do I fix it??
