Hi guys,
So it is now 1st of January here, there seems to be graph error with my whmcs setup. So I decide to check my reports page as they are plenty of graphs there. The result? At first, only the graph won't load at first. Then every other pages of whmcs, let it be admin or client section just wouldn't load. It'll be just a blank page and a never ending page loading. Httpd process will use up 100% of my cpu. Non-whmcs pages load just fine though.
Attached is a screenshot of the graph error in admin's home.
