Solved Players can't craft items!

I am having this strange error after I updated to the latest version of Bukkit. This happened yesterday after I installed a new plugin. Players are unable to craft any items even after restarting the server. I am OP and even I can't craft.

8. None

9. Previous time it happened I attempted to restart the server, with no result. I had to resort to loading a backup but I do not wish to reload a backup again as players will loose items.

10. No

 

try removing the plugin

 

I don't think the plugin could be causing it. The first this happened I loaded the backup and installed the plugin and it worked fine. It has been working fine for the past day but as soon as I updated Bukkit players couldn't craft.

 

try downgrading and see what happens

 

Strange, it just started working for no reason at all. I'll update this thread if it happens again.

 

lol ok mate
