okay i will check this, i have write a patch for my own client a i have to little data from trainer position… the data base for trainers is a mystery for me, i understand, the professoin id, trainer id, the npc id a the location – mystery… so i can’t fix it by myself 
EDIT: In fact dugi, i can say, profession ID for herbalism ( you use 2366) is wrong, use ID 9134, this is the correct ID to give the right name for herbalism profession on Classic….
