 * Hello,
 * Dont know what happened but suddenly I get those errors in the backend:
 * **ables should be passed by reference in /home/hostin1q/public_html/wp-content/
   plugins/w3-total-cache/lib/NetDNA/NetDNAPresentation.php on line 28**
 * Not one time but multiple times. Am I the only one with this error?
 * Kind regards,
 * Joep
