This is on an install of 5.3.9. This is not from an upgrade.
The Web interface does come up. But it has the yellow bar across the top that the configuration has changed. The problem above happens when I
click Apply. I get an infinite loop of bad gateway error popups.
If I run omv-firstaid from putty, it comes up. If I run Web Configuration and enter port 80 I get a bunch of errors, and the webpage displays "502 Bad Gateway".
