 * Hi
    I cannot activate the plugin. I get the following message
 * Fatal error: Call to a member function query() on null in /home/xxxxxxx/public_html/
   wp-content/plugins/xeroom/xeroom_indexInit.php on line 21
 * which refers to
    $licenseTable = $wpdb->prefix . ‘xeroom_license_key_status’;

 * Normally I wouldn’t repost my request but considering your history I guess my
   hope for an answer are slim.
 * First a while back I sent you the same question through your contact us page 
   on your website. Never got a reply
 * Second I see no answer on this forum to any of these requests.
 * Hard to comprehend coming from a commercial plugin developper that claims to 
   beat the competition. Hard to know if I can’t even install it

 * Hi Francois
 * This was resolved in a private email chain. For the benefit of others it was 
   caused by a conflict with another plugin but you haven’t been able to identify
   which one. You disabled all of your plugins and then it worked ok.
 * Thanks
 * Pete
