yes it used to work before.
This is due to your template, because 1) Deactivating other plugins change nothing, and 2) I tried with other templates and it works fine with them. Which is why it makes sense to get support from you and not from WP Bakery.
If it’s worked before then how comes it stop working? Can you remember the last action that you did into your site?
Also seems like WP Bakery is a premium plugins and it’s hard to investigate for us to resolve those problem, So could you please share us your login credential to your site here.
