Problem/Bug Why the smilefun plugin is in error?

I installed the slimefun on the spigot 1.9 server and run it. Then it showed the message:Could not pass event ItemUseEvent to Slimefun v4.0.13.I could not open the book gui.I don't know how to solve this problem.

And this is the server's log

Code:

I wonder if somebody can help me.

I changed the setting 'default-view-book' in file config.yml to false.But it doesn't work...

 

@LittleK
The plugin is outdated, are you on the latest version? If you are, try contacting the developer and asking for an update.

 

@AlvinB He's on latest one, issue likely is he is using 1.9 and running a 1.10 version.

@LittleK Use version 4.0.9
