I tried the classic solutions by adding the following to wp-config.php:
define( 'AUTOSAVE_INTERVAL', 3600 );
but they didn't work. I still get the posts saved & "revisioned" every minute or so.
Also, every time I add media content, like an image, an entry is added to the wp_posts table.
How do I completely disable these features? What I want is to have only post entries in the wp_posts table, no other rev/auto-save/media crap.
