HTTP 410 (Gone) responses

Changelog

1.2.1

• The “Maximum number of 404 errors to keep” setting is now capped at 10,000 to prevent unbounded growth of the logged-404s table.
• Fixed the “Recent 404 errors” pagination controls floating away from the table above them; they now stay aligned beneath it.

1.2.0

• Bugfix: Fixed a bug where selecting a large number of logged 404 entries (or 410/wildcard URLs) and submitting the bulk “Add”/”Delete” forms could silently reload the page without making any changes. This happened because very large selections could exceed PHP’s max_input_vars limit, dropping the nonce/action fields the plugin relied on to detect which button was clicked.
• Admin bulk actions are now identified by an explicit hidden mclv_410_action field (emitted, along with the nonce, before the checkbox list) instead of by which submit button was clicked.
• Bulk operations now submit database IDs instead of full URLs, and are processed with chunked WHERE gone_id IN (...) queries instead of one query per row.
• The “Obsolete URLs”, “Wildcard Patterns” and “Recent 404 errors” tables are now paginated (100 rows per page by default, filterable via mclv_410_admin_per_page) so the admin page never has to render or submit an unbounded number of rows at once. Pagination works without JavaScript, and “select all” only affects the current page.
• Admin form submissions now use a Post/Redirect/Get pattern, so reloading the settings page after a successful operation does not repeat it.
• Notices after an admin action now report specific outcomes (e.g. “182 logged 404 entries were added to the 410 list.”) instead of a generic “Options updated.” message.
• Bugfix: The page-caching notice no longer implies that an unsupported caching plugin has been detected merely because WP_CACHE is enabled. It now describes page caching as informational, explains this is expected with W3 Total Cache and WP Super Cache, and notes that other caching systems (including host-level caching) may need configuration.
• The manual “add URLs” textarea now accepts a maximum of 500 URLs per submission, with a clear notice if that’s exceeded, to avoid very large pastes running into PHP execution-time limits.
