Hi,
Biomes o' plenty wont work on my minecraft, as is says in the link, the version of forge is too old, but i took the recomended one, all of my other mods are working.
i tried googling the forge version, but its none existing.. whats wrong?

Thanks

What version of Biomes O plenty are you using?

http://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.7.10.html This isn't a bug, 'Recommended' Forge versions are rather meaningless really, mods require whichever Forge version has the features they use in their mod.

I have literally used all of the different forge versions, non of them are working, at all.

Are you sure you're not trying to run a 1.8.9 version of Biomes O' Plenty with 1.7.10 Forge?
