moderator problem

I have a moderator, but when he tries to delete a post, it's states "only administrators can delete posts in this forum"

i have already appointed him as a mod of that particular forum.

So, you have set him as the moderator to the forum via your permissions and admin panel?

general -> messages and emails -> Message edition duration limit for a member -> check none
maybe this can help

i've done all of the above, but still have the same problem.

i don't know then, i had the same problem and i resolve it like i said, sorry .. . .
