website.com/admin Redirects to Post?

Hello All,

One of our clients is having an issue getting to the admin page. She created a post that started with the word admin (https://crestonwildlife.ca/admin-office-closure-march-4th-9th/) and now whenever she tries to log in using /admin it redirects her to that page.

Does anyone know why this happens? Why is it redirecting to a post instead of going to the admin login?

Note; I know she can use something else like /wp-admin or /login, I just want to know why this happened and how it could be fixed because I can’t find anything on google regarding this issue. Also, she’s using Elementor for her website/posts.

Thanks!
