Internal Server Error when logging in to my custom modpack

[darkzealot42]

As it says on the tin, I have a custom modpack. When I try to join the modded server however, I just get an internal server error and it doesn't really say anything about a specific mod other than forge itself. the error i get is the infamous "java.lang.nullpointerexception" error. here is what the server log says: (Please note the server is still functioning, I just can't join)

OK,

I know that support isn#t offered for that old Version, but it looks like some mod on the server side needs another mod (Like NotEnoughItems needs the CodeChickenCore)

 

The first Exception mentions this "missing mod".

 

The second Exception means, that your client sends some data to the server, but the server doesn't know what to do with that data. Maybe the former mentioned missing mod would handle that data.

I still get the Java.lang.nullpointerexception error:/
