If you have come across a warning that says "This version is incompatible with the profile modloader..." and reached this article, we're here to help!

This warning icon will be displayed when a mod that isn't compatible with a modpack's modloader is installed to that modpack (whether manually or through the app), or an installed compatible mod is updated to a later version that is incompatible.

To fix this, you can either update the mod or install a previous, compatible version.

What are the differences between the modloaders? 

When browsing for modpacks, adding more content to modpacks or editing projects as an author, you will notice a distinction between different modloaders: Forge, Fabric, NeoForge and Quilt.

The modloaders help enable Minecraft modding as you know it in the CurseForge app.

You can read more about Forge , Fabric, NeoForge and Quilt documentation and the idea behind them.

When authors submit their mods, they add tags to indicate which modloader the mod is compatible with. They may also upload different files for the same mod, to support multiple modloaders.

In order for a file to be compatible with a certain modloader its author must tag it so. Without this tagging the file will be marked as incompatible even if it works in-game.

When you edit a project as an author or create a custom modpack you should keep in mind the modloader type, so that you only add mods compatible with that modloader.

Note that not all mods are available for all modloaders. This may affect the type of project/custom modpack you prefer to create.
