iamlos3r Posted January 3, 2019 Posted January 3, 2019 Today I was trying to load up my mod pack I just created, it crashed half way through prep, and displayed this error code. Error: java.lang.NoClassDefFoundError: cpw/mods/fml/common/IWorldGenerator How do I fix this? The crash report is in the files. crash-2019-01-02_22.57.06-client.txt Quote
Cadiboo Posted January 3, 2019 Posted January 3, 2019 It means your trying to load a mod that was made for 1.7.10 or lower on 1.12.2, make sure all your mods are for the appropriate minecraft version & only download them from CurseForge or the authors website Quote About Me Spoiler My Discord - Cadiboo#8887 My Website - Cadiboo.github.io My Mods - Cadiboo.github.io/projects My Tutorials - Cadiboo.github.io/tutorials Versions below 1.14.4 are no longer supported on this forum. Use the latest version to receive support. When asking support remember to include all relevant log files (logs are found in .minecraft/logs/), code if applicable and screenshots if possible. Only download mods from trusted sites like CurseForge (minecraft.curseforge.com). A list of bad sites can be found here, with more information available at stopmodreposts.org Edit your own signature at www.minecraftforge.net/forum/settings/signature/ (Make sure to check its compatibility with the Dark Theme)
