Provide an updated log please

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.

It should be printed to the server's log as well as in the name of the server jar itself

This is described in the EAQ thread as well as my signature below

Try running vanilla for the desired version first

delete your logs folder and run the game

Try following the instructions in my signature for launching a Twitch pack without Twitch

Try repairing the pack, Twitch appears to have screwed up Forge's installation process

This is a 1.10.2 log...

You still have the JEI maven in your buildscript repositories block

So what you're saying is you copied these lines into the buildscript block despite this line saying not to mess with the lines above? Why?

I was going to say it goes where you see the examples for such, but for some reason those examples have been copied into the buildscript block, are you following a tutorial?

I asked for the screenshot as proof that you removed Optifine, you have just invalidated that completely. Post a log without Optifine.

Xaero's Minimap needs to be updated for a change in Forge

He didn't bump, he posted to two other people's threads before making this thread after being told to do so, I merged his hijacking posts in here.

Silent's Gems is trying to fire an event through Forge's Event Factory using a method that had its signature changed 2 days ago. If you don't know what that means, Silents Gems need to be updated to account for a change in Forge.

Make your own thread.

Do you have all mods installed on both the server and client?

Yes

Please refer to my signature, I notice you're using Twitch and the log file I want requires a bit of extra work to get in this case

It is the responsibility of the closed-source mod to adapt to the open-source mod, yes?

Have you tried removing Optifine?
