Login URL

Hi,
If you can’t change the default /wp-login.php ensure you filled a valid value at WP Hide > Admin >Admin Url. Try to keep the default url un-blocked, at the same menu location.
If use a cache plugin, ensure to clear the cache. Also, check if there’s a cache layer at the server level or CDN ( if use such thing ).

If still not working, this is caused by the server configuration, you should get in touch with the server support and ask for additional details why the rewrite for custom URL is not processed correctly. Probably there’s a firewall rule which does not let you access files if they do not exists on the server, even if being re-mapped through rewrites.

Thanks
