@khubaibch I fix it. My solution –
1. Delete all drafts from DB with WP-Optimize plugin
2. In table wp_posts to post_date, post_date_gmt, post_modified, post_modified_gmt
set default value CURRENT_TIMESTAMP
3. In ID add AUTO_INCREMENT
Now it works. But I am not an expert in this, perform actions with the database at your own peril and risk.
Hi, @khubaibch have you fixed the site? I have the same errors and no idea how to fix it
