Sorry, I'm the one who's behind, I forgot to update the announcement.

Take a look at the "Logs" section of my signature or read the EAQ.

Could you please provide a debug.log

Please provide an installer log.

First can I ask what this coremod does?

What version are you trying to use?

How did you install Forge?

Please read the EAQ or my signature and provide your debug.log

Spigot is not supported here and they appear to be the origin of this crash. It's also their watchdog killing the server, so I would assume it's because the server was running too slow anyway.

I would assume the computer you are running this on has internet access, is this correct? This computer isn't on a weird network (i.e. a college internet connection that filters traffic), right?

It's a cracked launcher that they have been banned for using.

from CurseForge, yes. (Note: CurseForge is not the same as MinecraftForge)

Please provide a log from the official launcher.

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

Please don't hijack threads, make your own.

Please read my signature.

Where are you getting your mods?

I mean use java -jar [Forge Installer File Name] --offline

--offline is an argument for the installer

Yes on a terminal

You may have a network issue, try running it with the --offline flag

What launcher are you using?

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

One of your mods is broken and trying to access client-only code from common code. I can't tell which mod from the information you've provided.

What exact version were you trying to install?
