Wow Character immune to everything

Im a lvl 70 Preservation evoker. Went through a dungeon and realized i cant pick anything up from chests. Went to do quests where i need to pick up items and cant do those either because my character is “Immune”. Ive jumped off high spots, tried fatigue death and everything. I cant find a way to make my character un-immune and as of now i dont take any damage at all, in a duel or anything.

Dont want to get banner or something but this needs to be fixed.
