I'm using version 2.0.7 but I've been using it with no problems up to now.
It was only yesterday late that I decided to do a quick check with
http://localhost and got an error 403 for my trouble rather than
the display of default-web-app\index.html I expected.
I have been messing about about with various Orion files to get the example Standard Web App ("bee" between Servlets-3a and 3b) running, so maybe this has some bearing on the problem.
I'm going to try commenting out the changes I made, to files in orion\config and see what happens.
Any other thoughts more than welcome!
