Just updated from 3.1 to 3.42, and got everything back to "smooth" status.
But I am getting email from readers who say they are getting the White Screen of Death. I tore the whole install apart, and followed all the steps to a dozen or more search pages. No joy.
In the end, I narrowed it down to a URL problem.
When I type in http://www.mysite.com, it works fine (this is the value in "settings" by the way).
When I type mysite.com, it is the White Screen.
This was not the case prior to the upgrade.
Is there some kind of alias I need to add to a config file to fix this?
Thanks for any help y'all can lend.
