Jackie McBride on "Cannot Delete or Replace a Page"

Hi all,

Been working on solving this mystery for the past 3 hours with no avail so hopefully someone can save me here.

Here goes:

1. I created a Testimonials page for my website today.

2. I decided the page did not look very good and proceeded to delete it from Pages --> Trash --> Delete Permanently.

>>Here's where the fun begins /sarcasm<<

3. I click on Pages on the sidebar and see "Private(1)" but when I click into it, it's empty.

4. Confused as hell, I eventually thought to see whether the old page (the one that I just deleted) was still there (mysite.com/testimonials) and lo' and behold, the page now says "Archives: Testimonials" with all my previous content.

5. No matter what I do, I can't seem to delete this page. Things I've tried:
- moved all my testimonials into the trash --> page just says "empty" but still exists
- created another "Testimonials" page in Pages --> previous content refuses to be replaced and new page (with new content) doesn't even show up.
- restored previous backup, still has /Testimonials even though content isn't even in this prior backup
- cleared cache and tried using both Mac and PC

I'm. So. Confused.

Help.
