With the expected message I 've got before when OS X server claimed FM's ports (and OS X server had websites off) :
Websites are turned off. An administrator can turn them on using the Server application.
This ties is with the known issue on OS X Server and Filemaker port conflicts for websites, but my issue is that I didn't even turn on OS X Server... I have it off with not possibility for upgrades and not using it, until an official fix comes out.
And my query is: What is the quickest way/hack to reclaim said ports? I am not interested in the full technical brief hack for virtual websites, I just want to know if this happens again how can i fix it quickly, when restart doesn't work.
