PermissionEx not loading correctly

Ive been having trouble getting my Permissions file to load correctly and am getting these errors. Here is the console when I try and start the server.

Code:

Actually I fixed my issue but now the server is unable to load prefixes because I do not have a plugin to read them. Is there one that you can suggest because EssentialsChat is not working.
