Single post sidebar problem

Hello,

If you want to remove marked elements, please disable also "Shos sidebar information" option from post additional params metabox.

"Shos sidebar information" but date, author hide

there's no other option to hide these elements, you can try to remove them from the theme code.
News/gavern/helpers/helpers.layout.fragment.php file and gk_post_meta_sidebar function - but in this case these elements (permalink, edit) will be removed globally from all posts.

Thank you
