I solved my problem by adding define(DOING_AUTOSAVE, true); on 104 line simple-page-ordering.php
I am having this same problem. Is there a chance this fix will be added to the plugin?
@malakhovmisha is your problem with the custom post meta only on CPTs that have a “custom column” displaying this meta? I think that could be why this issue has not gotten much attention. Please confirm if this is the case for you as well.
I have issued a pull request to the plugin github account with the above fix in place. Also I have been tracking the issue there.
Hope to see a resolution to this, because the plugin is awesome!
I Verified the code was my problem. if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE )
was set to return $post_id;
when it should only return;
