[help]the waterfall unable to show - tudou527 - 05-08-2012 10:55 PM zlib extend hass loaded in php, and the "Full Optimization Checklist" is normal. Can someone help me? RE: [help]the waterfall unable to show - pmeenan - 05-09-2012 12:45 AM Do you see anything in your error logs? If you click on the blank waterfall, does a large version of the waterfall load or is it also blank?
