php link not found error

I recently started getting this error on my site :

The requested URL /ilanlar.php was not found on this server.

although the link is correct and I have set the path and everything correctly, the link I try to access is as follows :

http://ift.tt/1KQ5czY

here the surprising thing is, I have the link defined as:

<a href='http://ift.tt/1IkfLrp'>CLICKY</a>

but the %EF%BB%BF part is being added automatically on its own, what am I missing here?
