WordPress’ Autosave feature was getting on my nerves. Often I make several revisions of a page before I save and WordPress was saving intermediate drafts that I didn’t want to keep.
I was surprised to find that there is no option in WordPress core to disable Autosave. Thankfully though it is incredibly easy to disable through editing the source or creating a custom plugin.
The following code (take from the reference link below) will function as a WordPress plugin and will disable autosave (works in WordPress 2.8)
<?php /* Plugin Name: Disable Autosave */ function disable_autosave() { wp_deregister_script('autosave'); } add_action( 'wp_print_scripts', 'disable_autosave' ); ?>
