To avoid 404 errors, Permalink Manager Pro will automatically redirect also multiple custom permalinks used temporarily before the final URL was set. If you are using the free version of plugin, only the native permalinks (used before Permalink Manager was installed) will always redirect to the currently used custom permalinks.
What will happen after I change the custom permalink? Can I redirect the old version of custom permalink to the new one?
If you are using Permalink Manager Pro, you can enable “Auto-create “Extra Redirects” for old permalinks” mode in the plugin settings, the redirects will be automatically created for old URLs, after posts or terms permalinks are changed.
To adjust, delete or add another extra redirects please use the URI editor and click on “Manage redirects” button to display the list of active redirects for particular post or term:
Will the old permalinks be automatically redirected to the new ones after Permalink Manager is activated?
Yes, if “Redirect” option is enabled, Permalink Manager will automatically redirect the native permalinks (used when the plugin is disabled or before it was enabled) to the custom URL addresses you set. No additional action is needed.
