How to see newly written PHP errors and warnings while you work in wp-admin
Live admin alerts are optional and authenticated. When enabled, a lightweight AJAX runtime checks the configured debug log only while an authorized admin page is open and shows newly appended errors or warnings inside wp-admin.
Configure the alert behavior
- Open the WordPress debug logging card and find Live admin log alerts.
- Enable live admin alerts. The setting is saved without requiring you to expose errors on the public site.
- Choose how many seconds each alert stays visible. The supported range is 3 to 60 seconds.
- Choose Always visible at viewport top when you want alerts pinned while scrolling, or Top of admin page when they should remain in the page flow.
- Open another wp-admin page and reproduce the issue you are investigating.
- Use the alert as a prompt, then open Error Intelligence or the raw log for the complete diagnostic context.
