Posts can't edit and create

I trying to edit a post but I can’t because I can’t see the editor and the content of the posts like the photo.
I think that it happens since I change the version of wordpress, but I don’t know.

Please help me!!


Please try to temporarily deactivate all your plugins except aThemes Toolbox and Page Builder by SiteOrigin, and see if it helps.

Kind Regards, Roman.
