What is wrong with your current version of forge. If it works leave it with what the mod pack came with. You don't need to update your forge every time there is an update available unless a mod specifically requires it. Twitch is designed to make it easy for users to download premade stuff if you want to mess with stuff install it using the forge installer and run it with the Minecraft launcher.

If you are just going to install forge with your own mods use the forge installer jar. Then launch it with the regular Minecraft launcher.

What problem are you experiencing please post your logs as described in DaemonUmbra's signature?

I would make a backup of your server. Then on the copy of it clear your inventory with MCEdit. Let me know if that works.

You can keep them you just won't get as much help when things break.

This depends on how the mod was coded. If they followed the forge policy the core mod would just contain the code needed for the hooks and such. Then a separate mod would contain all the items and blocks that would utilize that hook. Coremods allow you to do things that you normally could not do. The problem is most people don't know how to code things right and since core mods can do more they can break more. They are also very complicated making it even more difficult for the people who have no clue what they are doing to do it right. This especially goes when you make a core mod even though there are other available options such as creating a hook and adding it to forge yourself. There are a few core mods that I think are pretty well made but most of them bring more problems than they are worth.

Yea, I recommend you open the world in MCEdit and remove that block.

Try turning off the mipmap setting in the main menu before opening a world.

Try loading up that server with all the mods except IC2 see if the issue comes back. If it does not add IC2 then see if the problem happens again.

Applied Energistics is crashing. Try to update it or contact the mod authors for more support.

Sorry I might have miss read your issue. Could you set up another server without any mods and start and stop it a bunch to see if the issue persists. This will help us eliminate if it is a mod that could be causing it.

If it is only those ports I reccomend you use another port. Some program may be trying to do something on those ports. When the server is not running run a port scan on your computer and see if they are being used by a specific program.

No forge will never support bukkit and spigot plugins. There have been many attempts to do this and all of them have more or less failed. The closest you are going to find to something that you described you should look into sponge forge. You can also find most features that plugins implement in the form of mods. The other option is you learn how to code and implement the features you like from plugins into your own mod.

This should not affect any player data. This would have to do with how multicraft hooks into Forge. If this is an issue for you I recommend you downgrade to 14.23.4.2705 as it is the latest stable version of forge. You shouldn't have any issues downgrading. This is most likely not an issue with forge. Something multicraft hooks into might have changed causing these issues. This is something multicraft will have to fix on their end.

I don't this that would be the issue. Does vanilla Minecraft launch fine?

You are using Java 10 make sure you are using Java 8. Forge only supports Java 8 at the moment.

The links work fine for me. When you click the link to download the installer it will take you to adfoc. You then have to wait about 5 seconds, click skip and your download should begin.

That does not answer the question. Launch Command Prompt. Type "java -version" and press Enter. Post the output.

Does the issue happen with vanilla Minecraft? Have you tried a different keyboard? Are your drivers updated?

Could you upload the complete log? Is it generating a crash report if so please upload that as well?

This bug was already reported. It does not look like there is a fix for it or will be in the near future. https://github.com/mezz/JustEnoughItems/issues/1202

There is a very good reason we don't support 1.7.10 and earlier. There were a lot of mod breaking changes from 1.7.10 to 1.8 which is why so many mods stopped being updated. Now as we do recommend you try to stick to 1.12.2 we will also be able to help you with any version from 1.8 - 1.12. Whether it be issues with installing forge or the game crashing we will be glad to help. If you need anything else just let us know. You mentioned you were experiencing issues with the windows installer I recommend you use the jar installer this may fix some of the issues you are having. Make sure that you also only download mods from curseforge. You shouldn't have to manipulate your java version. Just make sure you are only using Java 8.

Check your internet connection make sure your antivirus isn't blocking Minecraft.
