WP Problem

Please excuse anything that’s not in mesh with how you guys do things. I’m new here, just signed up a few minutes ago. Lol.

I am trying to get my own hosted site to work with WordPress, which I did, but I accidentially messed up a setting somewhere with WP and redirecting.

For an example:
If I go to: https://mcnarypiper.com/wp-admin nothing loads.
If I go to: https://mcnarypiper.com/wp/wp-admin the login site loads.
When I sign into the login site, it redirects to: https://mcnarypiper.com/wp-admin/login.php and then locks up.

What do I do to fix this problem? I can’t get into the admin tools on my site. All help is greatly appreciated.
