 * When attempting to activate or preview GamePress, I get the following error message.
 * **Fatal error: Call to undefined method WP_Query::is_main_query() in /home/www/
   extended-replay.com/wordpress/wp-content/themes/gamepress/functions.php on line
   238**
 * I’m currently using WordPress 3.2.1, and was wondering if I should update it,
   or if there is another solution I should try first. Thank you.

 * Absolutely ASAP – running an old version of WP is a major security risk.
 * Be sure you make a full backup of your site before updating it and see:

 * You actually should see the extended upgrade instructions – since you may need
   to update incrementally :

 * Sorry it took me so long to reply, but upgrading did the trick. Thanks for the
   help, WPyogi. Much obliged.
