The requested URL was not found on this server

Hi all... I had the same sort of issue when I copied my files from one host to another... Back Office was working but not the Front.
After struggling for sometime i kinda found a way around the issue... (maybe luck   )

I just enabled "Friendly URL" under PREFERENCE > SEO & URLs and it worked for me...

Give it a try and l me know if you haven't found the answer yet and also if you have found a better way....
