My Classic editor is not working since I updated. When I try Get Media nothing happens and when I update existing pages or posts, I get an “oops page not found” Grr.
For my share, I can’t find the default options in the Writing Settings page. I need to be able to enable it on specific posts only. That renders the Classic Editor unusable for this particular project.
WP 5.9.3/PHP 7.4.29 on a single site (in a multisite network).
