After 4 activatations and performing complete and totally removal of all traces from folders and database after each, I spent almost 3 days every time I reactivated it trying to configure it.
When I eventually got to the point where I figured that I finally had everything working as it should and signed up at MaxCDN - I then discovered more problems with the MAXCDN side of things.
With W3T and MaxCDN, believe it or not - my sites performance dropped RADICALLY - If you working busy working on your site - dont even think of installing this, wait until you 100% ready and have the time to leave your site for days on end.
I need a break, my stress levels went through the roof and once I've gotten over this whole nightmare, i'll be back to post a comprehensive list of things that simply just didnt work for me!
