ExpertWP 404 Page Monitor

ExpertWP 404 Page Monitor keeps a list of the missing pages people (and search engines) request on your site, with a hit count and the date of the last visit. From the same screen you can send any of those addresses to a working page with a 301 (permanent) or 302 (temporary) redirect.

• See what is broken: every missing address with its number of hits, sorted by most hits or most recent.
• Fix it in one click: add a 301 or 302 redirect next to any entry; remove it again at any time.
• Light on your server: each address is written at most once a minute, the write happens after the page has been sent, and the log keeps at most 2,000 rows.
• Skip missing files: broken images, fonts and scripts can be left out of the log (on by default).
• Search and filter: find addresses by text and hide static files from the list.
• Works with any theme: your redirects keep working when you change themes.

The monitor is under Tools → 404 Monitor.

For theme developers

• pm404_menu_parent (filter) – the admin menu to place the screen under. Default tools.php.
• pm404_enabled (filter) – return false to stop logging (redirects keep working).
