Could you send the full log?

Please use a paste site such as pastebin and then send the link here. Your post doesnt actually tell us anything about the error other then you saying there is one

I have one further suggestion: try not to include client-side mods when testing. SpongeForge is primarily for use on a server, and client-side mods (like Optifine etc) can introduce more problems.

As Inscrutable said. Remove the client only mods from your server. It helps with compatibility. Even one of your mods is telling you do this

Optifine is installed. BakedQuads won't be squashed as it is incompatible with OptiFine

But you have a lot of mods that are on sponge’s mod incompatibility list (although almost all on that list have specific patches) so have you applied the patches?

one thing is that later testing without spongeforge the server just wouldn’t work so the issue isn’t spongeforge related
