I have a problem when I start my minecraft server.
I am currently using a Magma server (allows plugins and mods at the same time).

The error in question is this one:
java.lang.NoSuchMethodError: net.minecraft.item.Item.setTileEntityItemStackRenderer(Lnet/minecraft/client/renderer/tileentity/TileEntityItemStackRenderer;)V

I don't know what does that mean and what to do to solve it.

If someone can help me, I'll be so grateful. 

The version you are using is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.
