Mod Rejection Biomes o'plenty

Good Evening everyone,

I am fairly new here, but quite excited, well at least at the beginning, because at the moment stuff is not working right.

Tho I installed the mod Biomes o Plenty and changed the world type to "BIOMESOP", I downloaded the mod biomes o plenty and placed the file into mods in .minecraft . I downloaded Forge 1.12.2 as well, installed it and I started Minecraft chosing the Forge option instead of vanilla.

I can play with biomes o plenty in Singleplayer, but when I try to connect to my Multiplayer Server, it rejects the mod and puts the error:

Mod rejections [FMLMod:biomesoplenty{7.0.1.2325}]

I literally don't know what to do, does someone have a solution?

Any help welcome, best regards Nico

Nevermind, I used a newer version of Biomes o Plenty, just switched it with the BiomesOPlenty-1.12.2-7.0.1.2325-universal.jar and it worked out perfectly.
