Hi. A lot of players on my server are complaining about that the anvils are not working for them. Whenever they try to anvil their sword for instance, combinated with an enchanted book, it would just simply not work but their XP would be removed leaving them sad and wondering what happened.. The anvils are working just fine for me (as an OP) but as I wrote not for the normal users. I am using Essentials as one of the core plugins, could this be the problem? If not, am I doing something wrong? Are there any permissionsI have missed?
