 * When wp-cron runs, I get the following in error.log about 11 times per run:
 * Warning</b>: strpos(): Empty needle in <b>/homex/xxxxx/public_html/wp-content/
   plugins/wp-super-cache/wp-cache-phase1.php</b> on line <b>558</b>
 * I tried to google this error, and can only come up with a potential site url 
   variable issues. When turning on debug I don’t see this error anymore. I am not
   sure what is going on here.
