That error indicates that your php doesn't have enough memory allocated to complete the operation. You can either increase your memory_limit setting in php.ini to xxM or to temporarily up your limits edit your includes/config.php file and add this line right under the <?php line:

ini_set('memory_limit', xx * 1024 * 1024);

xx being the next step up in size... if you are currently set to 8MB, up it to 16. If you are set at 16, up it to 32, etc.
