I would like to know this too, because after the update the “text” panel and the “visual” panel that appear when editing a page have disappeared. All that I have now is the “pagebuilder” panel. If I click “pagebuilder” it changes to “switch to editor” but the other two panels are still not appearing.
With the SiteOrigin Editor widget this is the same. I can only type in text form. I do not have the options to format as I did before. E.g. heading 1, heading 2, paragraph etc.
Pictures also appear in text form and I cannot edit them using any other widget or in the visual panel (because it’s not there).
Could you please assist in this matter!!!
