Cannot Sell to NPC Vendors

[Reighna]

I cannot sell to any NPC or even delete items from my bag.
I have tried deleting the cache and going to multiple different vendors and it still doesn't work.

The vendors say they do no like me.
And whenever i try to delete an item it says "that item is busy".

Does anyone know how to fix this?
