Wordpress login fail after .htaccess domain redirect

Question

I use .htaccess to redirect requests to my (new) domain to another domain hosted on different server. The file contains:

Options +FollowSymlinks
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^(www\.)?amazon40\.com [NC]
RewriteRule ^(.*)$ http://steamsigs.com/amazon40/$1 [R=301,L]

The redirection works fine. The home page is redirected to steamsigs.com/amazon40 and wordpress login page shows up correctly (steamsigs.com/amazon40/wp-login.php). But the acutual login process doesn't work. It does not show the control panel and keeps on redirecting to the login page. Could be that something's interfering with the GET/POST vars but I'm not sure about this.

I'd appreciate any your help to resolve this.

Answer 1

Did you also change the site URL in the settings? WordPress needs correct settings for these, otherwise the login page on steamsigs.com will still do the post to amazon40.com and you'll never get the correct cookies set.
