Cant send my Nifflevar Bearded Axe from horde to alliance

It says its BoA, so i should be able to send it but when i try it says internal error or something like that

You may have a enchant on your Item left? ( like a poison or a shaman enchant )

( also you CANT send gold with the item anymore from Alli<->Horde )

I have runes on them. Any way to remove them?

Buy a low cost enchant in the ah and place it on the item. ( Like windsong or ele blast or even lower ones with just atk power + )

Thanks man, it worked!
