REST API Error Log Under Tools
Records REST API requests that fail with a 4xx or 5xx status, with the route, method, user and error code, and lists the latest 100 under Tools > REST Errors for debugging integrations.
Show PHP Errors to Administrators With ?debug=1
Lets administrators see PHP warnings and notices on screen by adding ?wpide_debug=1 to any address, while visitors and other users never see them, even with WP_DEBUG_DISPLAY off.
View the Debug Log in the Admin
Adds a Tools > Debug Log screen that shows the last lines of wp-content/debug.log, so administrators can check errors without FTP access.
