I have a problem with loading my website which is made with Prestashop. 4 or 5 months ago it was working fine, but today when I tried to open it it gives the me message Unable to open file or sometimes it gives me a server error. I have already tested a die('999') when the index file is loading. When refreshing it, it gives me the result 999 instead of the message unable to open the file. I don't know what happened to my website.
