checklink: Usually the sign of a malformed URL that cannot be parsed by the server

Hi,

trying to check :  www.mrit.com/Essais/test.php

I get an error : "Usually the sign of a malformed URL that cannot be parsed by the server."

There is a "require" and relative paths, but AFAIK, there is no error  and the page can be displayed properly with the explorers I
tried.

Thanks for help.

Martin
