Login to your database and run query:
SELECT * FROM wp_mds_options WHERE option_name = 'active_plugins';The result would look like:
a:8:{i:0;s:21:"polylang/polylang.php";i:1;s:49:"3d-flipbook-dflip-lite/3d-flipbook-dflip-lite.php";i:2;s:51:"all-in-one-wp-security-and-firewall/wp-security.php";i:3;s:36:"contact-form-7/wp-contact-form-7.php";i:4;s:49:"gallery-block-lightbox/gallery-block-lightbox.php";i:5;s:30:"seo-by-rank-math/rank-math.php";i:6;s:21:"sierotki/sierotki.php";i:7;s:61:"theme-translation-for-polylang/polylang-theme-translation.php";}
This format is a php serialized array. You can deserialize, edit and serialize it again using build in php unserialize() and serialize() functions. Or you can use it as it is (red more about php serilization).
If you see "all-in-one-wp-security-and-firewall/wp-security.php" in your output, then you can be almost certain, that you have also used AIOS plugin to modify your login path.
Now run another query:
SELECT `option_value` FROM `wp_mds_options` WHERE option_name='aio_wp_security_configs';Result: (not presented)
This will return configuration setup of AIOS plugin in similar output but slightly longer from the previous command. Close to the end of the string, you should find “aiowps_login_page_slug” key with the value. This value is your WP login page slug.
