Problem 1.7.10 Server Crash

[The Radiant Dawn]

Hello, I recently had a server crash and I don't know what to do to fix it. My server crashs everytime I start it. It has been working very well until now. I'm using the FTB Infinity evolved 2.6.0 pack to which I've added some mods. The server is hosted on a minecraft server provider. (OMGServ)

Can someone help me please ? =o

Never mind sorry, It was just a problem in the configs of my server that I modified.
