First, do you have Optifine installed?

Second, you're only giving it a single gigabyte, I'd recommend 3-4G depending on how heavy the mods are, but even Vanilla would need at least 2G. This is not the primary issue here but is likely to cause problems later on.

Third, your hardware specs seem a bit lacking to me, unlikely to crash you but don't expect stellar performance.

Edited by DaemonUmbra

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

Video:

Spoiler

 

 

 

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]

    • My friends and I are modding to survive But recently I want to use cmd to open the server instead of making the single player game public But when I used two methods to start the server, I encountered two problems first A I used forge to install the server files Created using the original server jar The server was installed successfully and the mod was also loaded successfully. But after I replaced the world file with my survival map, I found that the mod items inside disappeared but could be taken from creation again. So I tried to install the server using forge first B I have studied forge for a long time but successfully installed it. But when I put in mods it crashed But mods can be installed on the server   我和我的朋友們正在mod為了生存 但是最近我想用cmd打開伺服器而不是把單人遊戲公開 但是當我使用兩種方法啟動伺服器時,我遇到了兩個問題 首先AI使用forge安裝伺服器檔案使用原始伺服器jar 建立伺服器已成功安裝,mod 也已成功載入。但是當我用我的生存地圖替換世界文件後,我發現裡面的mod物品消失了,但可以再次從創建中取出。所以我嘗試先使用forge安裝伺服器,BI研究了forge很久但成功安裝了它。但是當我安裝 mods 時它崩潰了但是 mods 可以安裝在伺服器上 我和我的朋友正在mod生存 但最近我想使用cmd開啟伺服器而不是單人遊戲公開   但是當我使用了兩種方法開啟伺服器時遇到了兩種問題   第1個A 我使用了forge安裝伺服器文件 在使用原版伺服器jar建立    伺服器安裝成功 mod也順利加載  但是我將我的生存地圖替換世界文件後發現裡面的mod物品消失了但可以再次從創造拿取  所以我嘗試使用forge安裝伺服器   第2個B forge我研究了很久但也成功安裝了 但是當我放入 mods 之後發生了崩潰 但是mods在1A伺服器上是可以安裝的 Ps 我用谷歌翻譯 so    
    • That’s probably not it because as I stated I’ve done it before. I did it like deadass 10 - 20 times when trying to learn to make this mod pack because I kept wanting to reset my profiles and such. So it definitely works, it looks like maybe the creephosting files were the things that couldn’t be reached I tried reading the crash log
    • I don't know if this is the right place or not, but I have put together a custom modpack and I am in need of others to help me. It's a questing modpack with a lore book i'm currently writing out through Patchouli, and i am in need of somebody who will assist me in making the quests for the pack. It's a Zombie apocalypse modpack inspired by Deceasedcraft  with a tinge of magic and RPG mechanics via Mine and slash. Is there anybody willing to assist me as i'm one person building a modpack I could also use help with optimizations since that's not really my strong suite.

    • Hello, is it possible to upgrade from server 1.16.5 forge to 1.20.1 forge without losing a thing? and how do I do it? You need to change "forge-1.16.5-36.2.35.jar, minecraft_server.1.16.5.jar" and other modes.
