what about the output of ps?
did you try the logfile stuff?
the rest of the web UI works?
will track this down - it's a config issue somewhere that we just need to track down and resolve.
To be sure - these are the only changes you think you've done?
You installed new 0.4.1 package (over 0.3)
You did the user permissions change to http
If you are open to it - I could remotely connect to your PC (with open ssh session) with you later this afternoon and walk through these checks much quicker.. You would be able to monitor the connection. Ping me if interested.
