Not much you can do with that it is a problem with the modpack and you should contact the modpack creator about this problem or try redownloading the .technic folder and the modpack

No, only this. I tried in another Launcher. But not working, the error is "Pixel Format not accelered". Can you Help me?

January 28, 20196 yr

Pixel Format not Accelerated usually means something is wrong with your Graphics Drivers

Edit: Source

Edited January 29, 20196 yr 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

Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
Make a launcher profile targeting this version of Forge.
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).
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.

Open a command prompt (CMD, Powershell, Terminal, etc).
Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
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
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)
Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]

Had the same thing happen to me, removing Optifine did the trick.

Forge Server - Unusually high idle load

I'm test running a private modpack on my own server machine. But for some reason it is using an abnormal amount of CPU (~55%) and maybe memory (9 GB) as well during idle. I tried using other modpacks like MC Eternal 2 and Create Chronicles as control and they all have significantly lower idle load (~12% and 4GB). I've been trying to troubleshoot this for a few hours but I'm at a bit of a lost.

Server Log: https://pastee.dev/p/Wl3KBnhy
Spark profiling tick over 50: https://spark.lucko.me/kAbtzAJu9E
Spark profiling threads: https://spark.lucko.me/IanyhmdE9f

Server mods are included in the spark profiler, the idle load stays relatively the same whether there's a player online or not.

Network protocol error with vanilla client and upgrading world.

Forge should be completely compatible with vanilla clients, and vanilla servers.
The issue seems to be that your old entities contain a Attribute at an ID that the vanilla client doesnt like.
As I asked on reddit, you should share your old save file, as well as the mod list the server was using before and after the update.
Give us information to debug and we could probably find the issue.

Using Online Tools are Cheating in Minecraft

Honestly, the answer should be no. It doesn't give you an unfair advantage. Its like using a piece of paper to check your math. Plus its not like you can 'cheat' in your own world.

Can someone make me a orbital dog cannon mod for 1.21.8 fabric just like flame frags videos? tamed, with armor and potted up?

This is not a Fabric forum, this is for Forge mods. And typically we don't do commissions/requests.

Does Forge have an official recommendation for handling config syncing?

Server configs are automatically synced to the client.
The mod configs are automatically loaded from disc when the files are changed.
There is a bunch of ModConfigEvents for whenever the respective event happens.
However, you could probably just get away with just reading the *Value field you make when creating your config.
