Dear, Niddy,
You did not provide URL of page we asked for, so we did the test by ourselves on your site and mentioned shortcodes work fine. Examples are in the Private Content area.
If you need any further assistance with additional customization and shortcodes, we recommend submitting a customization request to the WPKraken team.
Please note that additional customization in files is outside the scope of our basic support.
Kind Regards,
8theme team
