Developing a new site. I'm getting the white-screen-of-death every time I try to create a new page or post. I've deactivated all plugins, changed themes and tried 3 different versions of the wordpress core (6.0.2, 6.0.1, 5.9.8) to try and find a solution - nothing's working and all was fine yesterday. The error showing on the server logs is:
PHP Warning: Creating default object from empty value in /public_html/wp-admin/includes/post.php on line 742.
Can anyone suggest a solution? Is it an issue with the host server? Surely I've circumvented problems with the install by trying all of the above. I'm open to ideas.
