Error when changing domain

Hello,

I’m finishing a web site on a temp domain and need to migrate it on the correct domain name/URL.

The hosting and database don’t change at all, only the domain name that needs to point from an old server to the new one where we’re testing/developing.

I export the entire MySQL DB, change all references from the temp domain to the final domain and import it back. When I do so and change the DNS, the web site appears as it should with all the pages etc. BUT all the Page Builder info is gone.

Actually, all the content of the pages is now in plain text, not in Page Builder. If I try and elect Page Builder, it asks if I confirm to do so, I say yes and there the entire data is in a single editor and not in different sections/widgets/editors/columns/etc.

How could I fix this ?

Thanks for your answer !
