Server Crash 5 Seconds After Start

So I made a Rexxit private server and the server crashes 5 seconds after I join.

• If you are using Java 8, the -XX:MaxPermSize parameter should be removed. If you are using Java 7, it shouldn't need to be set higher than 256M.

• The above line in the crash report indicates that your -Xmx is set to 1G. The implication is that your server isn't being started with the batch file, and parameters, you linked.
• Are you using a server build provided by the modpack creator or are you creating it yourself from the client modpack? If the former, then you really need to follow up with EnderMedia. If the latter, why are you doing that?

I downloaded the server download from the modpack page and put the mods into forge.

Their server download should work right from the download. Extract and start. If it doesn't, then you need to take things up with them.
