No Worries. Presumably, not all web hosts need to be asked to change these settings, as the issue would be a lot more common on your Q/A.
So I'm guessing that web hosts that advertise themselves as optimised for Wordpress, would have this setting already in place, and that just because a web host offers one click Wordpress installations with Fanatastico, does not mean that their server environments are optimised for Wordpress.
I installed
Server Buddy and this gives warnings for several Server Configuration Parameters (see screenshot), but I am not sure whether these parameters would read any better on a web host such as Hostgator or Bluehost.
What do you think? (Apologies if I'm going a bit off topic)
