I moved my site from dev to live and I'm getting errors in the backend, though at the frontend all appears to be OK.

If I try to edit PageBuilder content at the backend I get 'Cannot read properties of undefined (reading 'data')' and if I click 'back to admin' it takes me to the development site.

The Dev site is still working fine.

It seems there is a setting somewhere which needs changing, I just can't see where.

Can you tell me what please..
