CMS CMS blank unless I add content.php to end of url
 

Yesterday I upgraded from 4.0.4 to 4.0.7 and now if I visit the url to my home page (CMS) I get a blank white page. If I add /content.php to the end of the URL it looks like it works fine.

I have done the search and have not found anyone with my problem.

Thoguhts?
