WP Bakery Backend Editor Not Working

Hi there,

I am having issues getting the WP Bakery backend editor to work, or just show up at all. There is no button that appears on the backend to launch (screenshot attached), and the button on the frontend that says “Backend Editor” brings me to that same page.

I have taken over a site that was built by someone else, so I admit I got a bit lost trying to untangle the change of page builder plugins etc… but I just updated everything and the problem persists.

Any help you can provide would be much appreciated!
