XMonad "Couldn't match type" error while recompiling

Been trying all day to get this config to work on my xmonad, but whenever I recompile I get this error:

lib/PerWorkspaceDirs.hs:22:37:
    Couldn't match type `xmonad-0.11:XMonad.Core.X' with `X'
    Expected type: X WorkingDirs
      Actual type: xmonad-0.11:XMonad.Core.X WorkingDirs
    In a stmt of a 'do' block: (WD cdirs) <- XS.get
    In the expression:
      do { (WD cdirs) <- XS.get;
           XS.put . WD $ (ws, dir) : filter (\ (a, _) -> a /= ws) cdirs }
    In an equation for `changeDir':
        changeDir dir ws
          = do { (WD cdirs) <- XS.get;
                 XS.put . WD $ (ws, dir) : filter (\ (a, _) -> a /= ws) cdirs }

lib/PerWorkspaceDirs.hs:23:23:
    Couldn't match type `xmonad-0.11:XMonad.Core.X' with `X'
    Expected type: X ()
      Actual type: xmonad-0.11:XMonad.Core.X ()
    In a stmt of a 'do' block:
      XS.put . WD $ (ws, dir) : filter (\ (a, _) -> a /= ws) cdirs
    In the expression:
      do { (WD cdirs) <- XS.get;
           XS.put . WD $ (ws, dir) : filter (\ (a, _) -> a /= ws) cdirs }
    In an equation for `changeDir':
        changeDir dir ws
          = do { (WD cdirs) <- XS.get;
                 XS.put . WD $ (ws, dir) : filter (\ (a, _) -> a /= ws) cdirs }

lib/PerWorkspaceDirs.hs:26:29:
    Couldn't match type `xmonad-0.11:XMonad.Core.X' with `X'
    Expected type: X WorkingDirs

    In a stmt of a 'do' block: (WD dirs) <- XS.get
    In the expression:
      do { (WD dirs) <- XS.get;
           return $ maybe "~/" id (lookup ws dirs) }
    In an equation for `getDir':
        getDir ws
          = do { (WD dirs) <- XS.get;
                 return $ maybe "~/" id (lookup ws dirs) }

Can anyone assist? Thank you in advance

Well, that setup is cool.  What does yours look like?  What changes have you made?

Re: XMonad "Couldn't match type" error while recompiling

Couldn't match type `xmonad-0.11:XMonad.Core.X' with `X'
    Expected type: X WorkingDirs
      Actual type: xmonad-0.11:XMonad.Core.X WorkingDirs

An error like this usually indicates that you're mixing different versions of libraries/modules. Often that happens because you're importing something that has been compiled against an older or newer version than the version you're using yourself.

Re: XMonad "Couldn't match type" error while recompiling

@Leavism, are you using both community repos and haskell-core?
