  I get this error “Creating default object from empty value in post.php” when I try to create a new post or edit an existing. If I use wp-sweep and remove revisions it works. What I have found in diagnosing this is if I have more that one revision I get this error. I can edit a page or post once than anything after that I get this error till I remove the revisions from database. I have minimal plugins active and does it on replicated test site with duplicated database. I have disabled all plugins and using very basic theme already, hello elementor but does it on any theme. Any suggestions?

  The blog I need help with is: (visible only to logged in users)

  nobody? When I debug I get the following error but the page content, title etc. is not null. This happens on existing pages.

  WordPress database error: [Duplicate entry ” for key ‘uc_guid’]

  INSERT INTO wp99_posts (post_author, post_date, post_date_gmt, post_content, post_content_filtered, post_title, post_excerpt, post_status, post_type, comment_status, ping_status, post_password, post_name, to_ping, pinged, post_modified, post_modified_gmt, post_parent, menu_order, post_mime_type, guid) VALUES (11, ‘2020-08-26 06:44:29’, ‘0000-00-00 00:00:00’, ”, ”, ‘Auto Draft’, ”, ‘auto-draft’, ‘post’, ‘closed’, ‘closed’, ”, ”, ”, ”, ‘2020-08-26 06:44:29’, ‘0000-00-00 00:00:00’, 0, 0, ”, ”)

  finally figured it out, it was caused by a transient index created in the posts table called uc_guid
