It was employed in wordpress 3.3 however when i upgraded did not work. Whenever I type url http://www.sitename.org/?email=John , wordpress instantly removes paramter and causes it to be http://www.sitename.org/ Because of this a few of the plug ins will also be no longer working.

Does anybody know if this sounds like wordpress 3.3.1 fix or I must make a move in configurations sections? or write inshtaccess file. I just read about % as GET parameters but tend to not understand, sorry I'm just trying to puzzle out. My .htaccess file contents

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Thanks, Solved. I'm not sure however when my pal disabled Search engine optimization wordpress plugin things began working. Still I haven't clue of the items happened. Anyways working for the time being.

Thanks.
