If somehow the list of Revisions at bottom of editor, is missing, here are directions to bring it back:
- Login to your cPanel.
- Access the cPanel File Manager Code Editor and navigate to your wp-config.php file.
- Enter in the following code towards the top of the wp-config.php file:
/* @package WordPress
// ** MySQL settings – You can get this info from your web host ** //
After that click on Save Changes at the top-right.
Somehow the define statement wound up on line #58. I copied it (commented out) & moved it up to line #16 & changed the variable from 1 to 3. So now Revisions list box is at the bottom showing the last 3 revisions.
