I may have goofed something up. I'm using MU... and three of my blogs cannot be accessed unless I add index.php to the end. For example, I can't get to http://r180.com/blog/win1040main/, but I can get to http://r180.com/blog/win1040main/index.php. But, this isn't a good option, because when I click 'home', I get the error 403. What do I need to do to fix this? Two other blogs are getting the errors as well.
