I’m sorry, but I did not find a similar topic. I’m going to increase site security with All In One WP Security plugin for Wordpress. Bruteforce attack protection option changes part of the link: /wp-admin/.
Has anyone had a similar experience? Plug-in creators write that this can break your site:
This feature can lock you out of admin if it doesn’t work correctly on your site. You must read this message before activating this feature.
NOTE: If you are hosting your site on WPEngine or a provider which performs server caching, you will need to ask the host support people to NOT cache your renamed login page.
