Class 'Dispatcher' and class ''Router'' not found [closed]

Question

What I did:

I make a project in CakePHP 2.2.3. It worked fine till I did some changes in css. What happened

When i refreshed the page in browser I get following error

Fatal error: Class 'Dispatcher' not found on my site path/app/webroot/index.php on line 91

Fatal error: Class 'Router' not found

FYI I had already cleared all the cache.

Must have done more than change the css. I would start all over if it's still new. – Blowfish

I am sure about that i even tried to add manual path in app/webroot/index.php but still to effect.. I was working fine and i was about to finish it. Sudden change occur. I even checked the library file but still not able to find the error.. The problem is on line... $Dispatcher = new Dispatcher(); – Tetrafluoroethylene

@AnmolChanana Not really. The problem is that it isn't autoloaded somehow. Anyway, revert to the last commit, and everything should be fine, yes? :) – Megargee

Thanks all, well I asked my senior and he gave me best solution. The problem was that something was not save or file got corrupted as I was developing on ftp directly.It was not saved well. I JUST RELOADED "LIB" FOLDER FROM FRESH COPY. and everything works again. – Tetrafluoroethylene
