My main page works, but all of my WP posts and pages return a 404 error and 'Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.' This happens for all posts, feed, and pages (such as 'About')
Other threads suggest checking out mod_rewrite and AllowOverride with my host, and my host claims it has not changed anything lately.
I was fiddling with my permissions a few days ago, might it have something to do with that? My wp-config is set to 744.
