I'm sure there is probably a simple way to fix this and I am a noob but, I installed a few plugins, and I couldn't build. So I started to remove every plug in one-by-one to see if I were to be able to build... I tried without any plugins and I was not able to build. Is there any anti build that comes with a recent version of bukkit or something? Help would be much appreciated.
You can't build near spawn unless you're an op or have 'spawn-protection=0' in your server.properties. Also, "Bukkit Discussion and Help" is probably where you want to put future support issues.
i would have assumed that this was caused by permissions, but without plugins, it could only be the spawn protection. But, are you able to build in SP? If u installed something like SDK Guns for SP, you are not able too build in MP too.
