I've been reading like crazy, trying to find someone with a similar problem...but to no avail. Here's the deal:
I have a bunch of wordpress-powered sites on shared hosting, and on all of them, my 'pretty' edits of permalink structure have resulted in the creation of an .htaccess file with no problems.
So, I'm working on another one, even using a theme I've used on two others...and no .htaccess is being created. So, my links don't work. I even copied the .htaccess from a nearly identical site, added it, but that didn't work either. It's acting like there's no mod_rewrite, but it can't be a hosting issue because all the other sites are fine. I upgraded WP, re-installed everything, and no go.
I'm officially stumped...any input?
