Wo-admin

Hello, I used WPS hide login to get rid of the wp-admin extension. But when changing back to wp-admin i can’t login to my website. I cleared the browser cache and with Nitropack the WP cache. Nothing works. This is my fourth restore of a backup as result of not working WPS hide.What’s goin’wrong here?
