Server crashes when joining

[E4RU]

Hello there! I am having issues after i removed the psychedelicraft from my modpack/server and added witchcraft and chisel mod. First when i booted the server up after that i got fml confirm message like i would normally everytime. I typed fml confirm to the console but it didn't respond tried restart and didn't respond so i mailed the host and they fixed it by adding the java flag to boot up script. After that server booted normally with weird errors but still it runned like it always does. So i joined the world and server crashed. Server is latest KCauldron and has always worked for me. Minecraft version 1.7.10.

I am suspecting that world has been corrupted. Can anyone confirm?
