[jakubkubik98]

Oh... i just checked my GitHub Repo and you're right... somehow one , sneaked into line 36. I don't remember putting one there. Thank you very much :)

You have to either remove OptiFabric or the MeteorClient mod

pls i'm need help for this, i have been trying to play mc with mods using fabric but every time I try I get this, I have tried everything, delete mods, install mods, etc, and nothing, please, someone who knows about the subject help me?

[Juuxel]

As the error said (in a pretty verbose way), you have a version of Fabric API that isn't compatible with 1.18.2. (Namely, you have a version for MC 1.19.)

You can get the 1.18.2 version from CurseForge: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/all?filter-status=1&filter-game-version=2020709689:9008

[TejKnight]

thx!

pd: I'm from another country and I didn't understand the language, that's why I asked for help

[darthpyro7]

I got it! I do not know what is happening! A few days ago it worked fine with no issues. I swapped Xaeros minimap for the Fairplay version and nothing else. Removing it does not fix this issue. Removing sodium did nothing either (it just said to remove xaeros) Please help

Your Sodium jar seems to be corrupted and Fabric Loader can't read it. Re-downloading should fix it.

Do you have Fabric API installed?

If it says install fabric, it means install Fabric API. It's confusing. Just install the Fabric API version for your minecraft version, which appears to be for 1.19.3 Release-Candidate 1. Try downloading from this page.

It states that you'll need to download a newer version of Resourceful Lib. If that still doesn't work, please join the Discord server and post in player-support.

Someone help pls.
I try to make a modpack with fabric.
When I'm put the "effective", "optifine" and "optifabric" mods together my game will crash.
Why is this happening, what is wrong with this three mods?

[Poopooracoocoo]

Effective no longer supports Fabric and has switched to Quilt. Effective will not work with OptiFine/OptiFabric. See https://github.com/ladysnake/effective/issues?q=is%3Aissue+optifine+is%3Aclosed

[l0V3MEsad]

pls help
I don't know exactly what the problem is, but I know what I did.
Note: I use tlauncher
first: I installed fabric on their website
second: I installed the api (any) and a mode menu (any too)
third: it didn't work at all, so i removed the resource packs, because tlauncher said it was a solution.
And here is the error code.

[liach]

@l0V3MEsad you installed the wrong fabric api, install a fabric api for minecraft 1.19.4

HOW DO I FIX THIS??

Mod resolution encountered an incompatible mod set!
A potential solution has been determined:
Replace mod 'Pehkui (Forge Version)' (pehkui) 0.0.0+forge with version 3.6.3 or later.
Unmet dependency listing:

Mod 'Extra Origins' (extraorigins) 1.19-4 requires version 3.6.3 or later of mod 'Pehkui (Forge Version)' (pehkui), but
only the wrong version is present: 0.0.0+forge!

[Poopooracoocoo]

If you post a message with your latest.log in the #player-support channel on the Fabric Discord server, you can receive help quite quickly. But it just looks like you've got the wrong version of Pehkui. You'll want Pehkui 3.7.5 for Fabric 1.19.4.

If you've already got that, what launcher are you using? And what does your mods folder look like? 😊

Please upload your logs or crash report to a paste site when asking for help to make it easier to read. You can find out how to do so on the Fabric Wiki. It may be more efficient to ask in the Fabric Discord server.

This thread has already been answered, however, and you seem to be having your own issue and are not helping the person you're "answering", so creating a new discussion or asking in the Fabric Discord server may be better.

It appears that all you're missing is Fabric API for your version of Minecraft which appears to be 1.16.5. You can download it from CurseForge

This thread has already been answered and you seem to be having your own issue and are not helping the person you're "answering", so creating a new discussion or asking in the Fabric Discord server may be better. I hope you've resolved your issues since posting here but in case you haven't, I'll do my best to help you out. :)

It appears that you're missing several dependencies for the mods you've installed on Minecraft 1.17.1. You can download them from CurseForge and Modrinth and add them to your mods folder:
GeckoLib 3
Kambrik
Flytre Lib
Balm
Fabric Language Kotlin
Cloth Config API

You also have the incorrect version of MC Dungeons Weapons and Second Chance

You may also want to clean up your mods folder to remove redundant old versions of mods. Using third-party launchers with support for CurseForge or Modrinth means that you won't have to worry about compatibility or cleaning up when updating.

This thread has already been answered and you seem to be having your own issue and are not helping the person you're "answering", so creating a new discussion or asking in the Fabric Discord server may be better.

It appears that you're missing two dependencies for the mods you have installed for your version of Minecraft, 1.20.1. They are Fabric API and ukulib. You can download them from CurseForge and Modrinth and add them to your mods folder.
