Can you pastebin your server logs? Have you checked for errors, either on startup or when trying to use a wand?

I fixed it I accidentally had my wand on blink. Is there any way to add mana to an item like if i wear a diamond chestplate i gain mana?

I guess I missed this follow-up question, but yes you can make armor that adds mana, such as the wizard armor included in the robes example.
