The problem now is every time that the restart appens the save.yml file gets empied so i loose my shopkeepers until i place a backup from it in the files and i restart then they are back but it is kind of annoying.What steps will reproduce the problem?

There exists a bukkit/spigot bug, which occurs when a plugin tries to save a custom player head item (a player head with custom texture property) to file.
Either make sure that you don't have any shopkeepers with trades involving custom player heads, or try out the latest shopkeeper version: The latest shopkeeper version should skip saving of trades involving those custom player heads -> the affected trades will be lost after reload nevertheless, however at least it should no longer clear all your other trades and shopkeepers as well.
