I'm looking at them both right now and the main page of my site is an intro page to the 3 sites I have and it's index.html. The store page is index.php. Would I need to change these to have index.php at the end of them?

shop configure file:
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');
define('DIR_FS_CATALOG', '/####/####/####/####/####/');

admin configure file:
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');
define('DIR_FS_CATALOG', '/####/####/####/####/####/');

I'm sure it's what I need to do but need affirmation before I screw it up. Also will this change the home link in the shop to say index.php? As mine takes me back to my intro page which is what I don't want.

If I also need to change it anywhere else let me know. Thanks
