Hello my domain working in this form http://myDomain.com but not working in the www form http://www.myDomain.com can any one tell me where is problem could be
make sure your .htaccess file automatically switches your website to the WWW version of your website --- ONE OR THE OTHER! you do NOT want google to index your website 1. as www or 2. without the www. This will cause problems with indexing and you might get penalized due to duplicate content [because it is indexing two versions of your site!]
Fix for this... in your .htaccess file, use this code:
RewriteEngine On RewriteCond %{HTTP_HOST} !^(.*)\.yourdomain\.tld$ [NC] RewriteRule ^(.*)$ http://www.yourdomain.tld/$1 [R=301,L]
this might also cause problems with adsense and such, so i recommend you do it asap just in case!
