Solved PermissionsEX Help!

My PermissionsEX has randomely stopped working. What should I do? The YAML parser was unreadable, I didn't know what I should do. Here is my PEX file.

Code:

I am greatful for any help and may let you be an Mod on the server. Thanks!

This is what the parser said.

Code:

Output
ERROR:
 
while scanning an anchor
  in "<unicode string>", line 228, column 18:
            prefix: '&a[Admin]'
                    ^
expected alphabetic or numeric character, but found '['
  in "<unicode string>", line 228, column 20:
            prefix: '&a[Admin]'
                      ^

What does this mean? Thanks!
(I have a TON of plugins installed, but I'm pretty sure that isn't the problem, PEX worked yesterday with the same plugins.)
