url redirected

here’s the issue:

• i have a private page at https://rrgcc.org/register.
• when i go to the page and i’m logged in, everything is fine, page loads as expected
• when i go to the page as any other user (ie: not logged in), i’m redirected to a specific post – i do not want this behavior

i’m not sure why it’s redirected to this post. i’ve:

• looked in .htaccess in the root folder, nothing
• disabled all plugins (i don’t have any redirection plugins)
• changed the slugs on the page and post, meaning that it’s not hard-coded anywhere that https://rrgcc.org/register goes to the post slug.
• searched my database for any references to “register-for” and/or 1331 and couldn’t find anything that would indicate the redirect

i’m at a loss. any ideas? thanks ahead of time..
