Within the file /inc/runtime.php reference is made to
index.php - a change should be made to how this file is
referenced.
For example -
a href= "/index.php? etc assumes that index file is in
document root and not in a directory.
So if phpwebsite is installed in /subdirectory
then /index.php is called instead of
/subdirectory/index.php
removing the "/" character from in front of the call to
file should suffice.
ie
a href= "index.php? etc
