Bukkit

I can click command signs when I am op.
when I'm not op (default), I can not right click on the sign (left click works)
Default have permission:     - commandsigns.use.*

I use cmds v1.9.3.2
Minecraft version is 1.8.3

I have this very same issue and I've been trying to fix it for literally 2 weeks. It's killing me. Bumping this to Pluto

I can elaborate on my situation if it'll spark some interest for someone who can help.

World1: default world when someone joins the server. I have multiverse. Tower: world someone can right click a warp sign and warp to cross-world However when someone wants to sign warp from the tower world to world1, they cannot right click it. Only left click, which spits an error into the chat box "unable to locate sign at x y z". The command both signs have is /*warp [warp] and all players have by default access to commandsigns.use* and commandsigns.use.warp someone please help

Hmm If players have the perms to use a sign (and you could try giving them the commandsigns.* perm, just to see if it works then... I would say it may not be an issue with commandsigns. Do you have any plugins that restrict other plugins per-world?

Beyond this, my only suggestion is to post the commands you are trying to use and we can see what the trouble might be, in case it's syntax-related.
