I to had a problem with the latest update 3.0.3. On my site I use Mantra with “One column, no sidebar“, but after the update all pages was changed to “Standardmall“. Then I had to change all pages back to “One column, no sidebar” manually. It’s disturbing to have to change more then 100 pages manually! I have another site using Mantra that I have not updated yet and I do not want to update before there is a solution for the problem. That site is more then 200 pages.
I am also using Elementor.
