Minecraft 1.7.10 is no longer supported on these forums. You will need to update to a more recent version to receive support. Also, repeat posting after less than an hour is considered rude, give people time to answer your question.

Also, you should update to a more recent version, I do no believe 1.8.9 is supported any longer.

That's a lot of complaining for getting something people put a crapton of work into for FREE. If you're so sick of waiting, why not chip in and help the devs? Pretty sure there's info all over the place on how you could help contribute instead of making a useless thread whining and complaining and asking to get banned.

Endercore crashing because there are Natura item references in the config file for items that don't exist? That would be my guess, based on just reading the first few lines. Often times if you read what it tells you, it gives hints as to what may be wrong.

You will need to update to a more modern version of minecraft to receive support here. 1.7.10 is really old, and no longer supported on these forums.

Looks like maybe underground biomes is trying to access client only classes perhaps? If you remove it, does it work?

You will need to update to a more recent minecraft version to receive support. 1.7.10 is very very old, and no longer supported on these forums.

Is the java 64 bit?

1.7.10 is so old, it is no longer supported. You will need to update to a newer version to receive help here.

You must have java 8 for forge, at least until forge for 1.13+ comes out.

Are you using Java 8? java -version will tell you I believe

https://app.twitch.tv/download This should make it easy for you. After you install it and run it, click where it says Mods near the top, then click Minecraft. This will allow you to install premade modpacks, or you can use "Create Custom Profile" to create your own modpack. Makes it much easier, and will make sure you don't download mods from a fishy site. Hope this helps!

The forge that this profile is running is outdated, even if you have a new one installed, you must edit the profile properties to make it use the new version.

Did you run the installer? Once it's been run, it should add the version to your dropdown, it is not installed in the mods folder like a mod, it's a little different. If you don't see it in the dropdown after you've run it, try scrolling all the way to the bottom.

Sorry, but you'll have to update to a newer version to receive support. 1.7.10 is really old, and no longer supported on these forums.

You should post the full log, partial logs only show part of the story. Post them to a pastbin or github or something like that for readability. =]

You will need to update to a newer version to receive support. 1.7.10 is super old, and no longer supported on these forums.

Hello! Playing with mods will only be possible if you have the Java version of Minecraft. If you have the Windows 10 version, mods are not compatible. If you DO have the Java version, then I would suggest getting the twitch launcher, found at https://app.twitch.tv/download This will prevent you from downloading mods from Bad Sites that contain broken/outdated/virused mods, and put everything in a nice package for you. After installing the launcher, just run it, and click where it says "Mods" near the top, then select Minecraft. From here, you will be able to browse packs made by other people, or create your own modpack by choosing the mods you want. Keep in mind when adding a bunch of mods, this can make the game run slower, and/or mixing mods sometimes they do not "play well" together. If you want a lot of mods, try adding a couple at a time, and trying the game to make sure it doesn't crash and is still playable. If you add a mod that breaks it, just go back and remove it. I am not sure what you mean by "I want to change my person", but I would guess that it means you would like a new "skin" for your player. There are instructions on changing your skin in the Java edition here: https://help.mojang.com/customer/en/portal/articles/979200-minecraft-skins?b_id=5408 Instructions for changing your skin on the Windows 10 edition here: https://support.xbox.com/en-US/games/game-titles/custom-skins-minecraft-windows-10-edition Hope this helps! Good luck, and most of all have fun!

Where did you get them from? If it wasn't curseforge, they are probably out of date/broken/malwared.

Try disabling the loading screen as described in the EAQ, see if that helps.

Did you try removing/disabling foamfix yet? If not, I'd probably try that and see if it helps.

1.7.10 is no longer supported on these forums due to it being super old. You will need to update to a more recent version (1.10+ I believe) to receive support here.

Have you tried running it without the gui? The one time I ran the server with a gui, it made things run slow, so if you haven't, try it without it.

I would try removing the netherrocks mod and see if it still crashes.

It means you're trying to load a client class on the dedicated server. It likely ran fine playing single player, because the client and server are physically the same (but not logically), but once you move the mod to a dedicated server, this will happen. The link about sides that Cadiboo posted should help explain it more.
