site developement: login problem

Hi there, first post here.

I’m trying to set-up a site.
I’m waiting for the domain registration so i’m still working on a “preview version” inside my hosting control panel (i use plesk).

My future site wull be https://www.domain.com
but for now i’m working at this address
https://192.168.254.254:8443/sitepreview/http/domain.com

I’ve managed editing site url and home using phpmyadmin, and i can see my site. but i can’t log in, everytime i try it redirects me to wp-admin/ at the root of my installation.

i’m looking at the wp-login.php file, but i’m not very good with php.

i think the part i should change is


if ( !isset( $_REQUEST['redirect_to'] ) )
$redirect_to = 'wp-admin/';
else
$redirect_to = $_REQUEST['redirect_to'];


but i don’t know in wich way.

if i do this

if ( !isset( $_REQUEST['redirect_to'] ) )
$redirect_to = 'https://192.168.254.254:8443/sitepreview/http/domain.com/wp-admin/';
else
$redirect_to = $_REQUEST['redirect_to'];

nothing happens.

I’ve no idea on how the login/password data goes to the system, so i can imagine a way to arrange this.

Any help would be very appreciated ??

Thanks,
Macmarty
