How do you load your share? Simply by selecting it in iTunes? If the webadmin is running, and iTunes sees the share, it should indeed show.
Check your log file. (/var/log/mt-daapd.log)
If it doesn’t exist, uncomment it in your config file (/etc/mt-daapd.conf) and restart mt-daapd. (/etc/init.d/mt-daapd restart)
If the log file doesn’t show anything, try raising the debuglevel to level 5 or even level 9.
Hope this will help you find the cause of the problem.
Btw: “Bonjour is stopped” is a bug in the older, stable version of mt-daapd. I guess you installed mt-daapd by running “apt-get install mt-daapd” which installs that version. Ignore it, it works fine.
