How can I disable post revisions?
Though it is not recommended that you disable post revisions, it is certainly possible to do so. You will need FTP, SFTP, or SSH access to your server in order to do this.
Step 1) Log in to your server with FTP, SFTP, or SSH
Step 2) Locate and open wp-config.php
Step 3) Add the following to wp-config.php
define( 'WP_POST_REVISIONS', false );
Step 4) Save your changes to wp-config.php
Note that in order to have post revisions, you can simply delete this line, as by default WordPress will always keep revisions.
