Well, Groupmanager has a build in anti-build feature and possibly permissions, too. Just look in their config files (in Groupmanager there was a 'build' node in the groups config file; right next to the prefix and suffix). Btw, Groupmanager and Permissions are both plugins for right management. I think they _will_ conflict if used next to each other (and you simply should not need both). I hope I could help you.
As Kiwii said. GroupManager and Permissions are both managers and actually WILL conflict with one another. I suggest sticking with Permissions and deleting GM. Edit: Also if you're trying to build in/near spawn area, you have to be set as op in your "ops" file where your server files are. Even though you may be an admin in Permissions you still have to be an op to build there.
