Hi there,
Thanks for writing in!
About this issue, you can try to deactivate all your plugin (once by once, except WPBakery Page Builder and TLG Framework) to see if the problem is gone or not.
Also, you can try to update your theme to latest version as in the article here: http://www.themelogi.com/knowledge/#theme_update
When you’re done on updating the theme, please go to your Dashboard > Appearances > Install Plugins to update your plugins.
Then you can click on WPBakery Page Builder button to use the page builder editor: https://i.ibb.co/jzBBN6R/wp.png
If the problem persists, please share us the admin account of your site via private reply so we can investigate your case and help you out.
Best regards,
Danny
