[SOLVED] Session expired or cookies not enabled error at CB Registration

Hello everyone,

I just released a new website that uses CB for user administration. It works perfectly on my localhost but on the server the frontend CB registration/login do not work (the administration section works). When I try to register it says "Session expired or cookies are not enabled in your browser". When I try to login it redirects to the same login page, without actually logging me in (no wrong password/user, the credentials are ok). I've disabled the cache, changed the session handler, extended the session time and still not working.

I even installed the non working version from the live site on my localhost, where it works perfectly, with no issues.

The Joomla debug system shows no errors.

The live website has the following specs:
Web Server: Apache
Database Version: 5.5.51-38.2
PHP Version: 5.6.27

The localhost, on which the site works great uses:
Web Server: Apache/2.4.17 (Win32) OpenSSL/1.0.2d PHP/5.6.23
Database Version: 5.5.5-10.1.13
PHP Version: 5.6.23

If you have any suggestions or ideas, please help me, I've run out of ideas.

Thank you!

It looks like the .htaccess code that redirects non www to www is causing this behaviour:

RewriteCond %{HTTP_HOST} ^lives-international.com [NC]
RewriteRule ^(.*)$ www.lives-international.com/$1 [L,R=301]

Then you probably have live_site configured as non-www within configuration.php instead of being '' (blank) as your redirect should prevent them from reaching non-www to begin with.

That solved the issue, thank you!
