Holy weapons requirement? (oops to delete please)

I failed find why a Holy weapon +1 wasn't working with my warrior Neutral Good. With a bard Chaotic Good it works, with Elmo (one Ranger level) is works. So it puzzles me.

Is it for most classes but warrior? Perhaps with arcane spell potential but it's seems this weapon can work with a paladin.

So any explanation why my fighter get zero bonus from it?

 

Ooop can some charitable admin delete the thread? I get screwed up by having changed my warrior setup to defensive fight and not even notice but with the new sword lol.
