Upgraded the very Domino server this blog is running on just now, 8.5.1 to 8.5.2.
Things went pretty well, the install was blazing fast due to the fact I am using SSD on the server.
After starting the upgraded Domino things looked ok, until I tried opening my blog http://nevermind.dk and got a 404. Huh??
I could access the blog by typing the full URL.
Something has changed in 8.5.2, since the Internet Site document

does not work any more.
Changing it to

made it work again.
The Domino server runs on Centos 5.5
Better check the other Internet Sites....
