LuxCal 4.7.1 - Calendar display problem in Safari, Edge and IE

LuxCal version 4.7.1 does not display correctly in the browsers Safari, Edge and IE. This problem can be solved by upgrading to LuxCal version 4.7.2 (recommended), or by applying the following fix:
Edit file index.php in the calendar root, and change line 80 . . .
from:

$calPath = './'.basename(__DIR__);

to:

$calPath = rtrim(dirname($_SERVER["PHP_SELF"]),'/').'/';

and edit file css/css.php and change line 14 . . .
from:

$calPath = './'.basename(__DIR__);

to:

$calPath = rtrim(substr(dirname($_SERVER["PHP_SELF"]),0,-4),'/').'/';
