I have installed Zoneminder and configured it.
Everything appears to be all right, (I have "monitor" and "dev/video (0)" in orange color.
When I click on "WebCam" (the name), I get a white box with no picture.
The webcam works using the "Cheese" program.
Any suggestions?

I had the same problem. Without the option: "Authenticate user logins to ZoneMinder (?)" it works fine.

I created a .htaccess (and .htpasswd) file in the root to solve my authentification problem.
