Jardi WordPress theme, can no longer access theme options and WPBakery no longer works

Hi, I recently logged into the Jardi WP theme and found out from an individual page that I can no longer access the theme options or edit in WPBakery. This basically means I can not do anything other than update or add content. No longer have access to add header etc.

Can anyone help with this? I’m wondering if it had something to do with a WordPress update. We have not updated any plugins.

Thanks! Molly
