Try these 3 options in the same order:
* Clear your browsers cache and try loading your website (
Steps for all browsers[

* If this doesn't work, delete the bin folder and re-upload your website
* If both of these options doesn't work, try uploading the site again, after deleting all the files and folders from your ftp account (make sure you have a copy of all the files in the ftp directory [if any] apart from your project files)
Hope this helps!
