Regex and config for redirecting all URLs, except /wp-admin and /specificpage, to a specific page within the same domain, using the Redirection plugin
The solution is extremely simple. Just create a rule redirecting all URLs to /specificpage with the position set as 1 (remembering to activate regex for the rule): ^.* And two “do nothing” rules, one for /wp-admin and another one for /specificpage, both with the position set as 0. That’s all.
