Link to another page not working

I am sure this is a simple problem related to the virtual nature of the files system.
I am using an Html tag linking to a log off page “logoff.php” The page destroys the session and does some clean up. Works just fine in native Php; but can’t find Logoff.php in the complied app.

What am I doing wrong? :?: :?: :?:

if you have your file in main root /logoff.php just use

if you have your file in subfolder /any/logoff.php just use

I didn’t see any problem with filesystem
