Thread:Project:Support desk/Problem with saving MediaWiki posts

I responded to a question here on Quora regarding a problem someone is having with (I believe) an installation of MediaWiki, by suggesting that he post his question here. His response was "I can see already that they can help but even after creaying an account with them it seems that they are also affected by the same issue: I can't start a discussion! The save button does nothing." ''

I don't have a clue as to (a) what's wrong with his installation, or (b) why it would impact his posting to a web page. If someone could help (either by posting here, and I'll play middleperson/relay, or by posting at Quora), that would be much appreciated.
