In IE i get this message
There is a problem with this website's security certificate
Now granted I just set it up like 10 minutes ago and would like to know if there is a propagation period for SSL cert's. I have never set one up before however I followed all the directions to the 'T' but its showing as a self signed certificate. This is one of the free ones you get when you buy a domain at namecheap. Will this warning always show or does it go away after s propagation period?

Does it have to be installed twice once for the www. and once for the none www? or should work both ways installing only once?
