New Base URL is not working
In your sites/default/settings.php file, comment the $base_url line, you don't need to specify one, Drupal can do it for you.
In your .htaccess, uncomment RewriteEngine on
In the same file, RewriteBase / must be  also uncommented, and if your website is hosted under a subfolder of your root web folder, you must specify your folder  here. Eg: RewriteBase /subfolder/
Activate clean URL's in admin/config/search/clean-urls
In apache httpd.conf file, check if mod_rewrite is enabled
