Hi! For me worked to shutdow autosaves. simply use this plugin:
<?php
/*
Plugin Name: Disable Autosave
*/
function disable_autosave() {
wp_deregister_script(‘autosave’);
}
add_action( ‘wp_print_scripts’, ‘disable_autosave’ );
?>
it is from here
I have wp-mu 2.7 and had problems with editing of posts/pages and this works for me. no need to convert categories… this problem was connected with autosave…
