Hi Ella!
Thanks for reaching out to support. I’m sorry to hear that you are having trouble with your page showing up as an archive today and I’d be happy to help see if we can get to the bottom of this with you.
I took a look at your page and in the source code it is actually indicating that it is a category archive:
Based on what we are seeing here, it seems that you have a Post category the use the slug earth
and that seems to be what’s displaying. Would you be able to check the Category base field in your Permalink settings? Normally a category page would show up under https://yourdomain.tld/category/earth/
but if you have a .
in the Category base field in your permalink settings the category and the page may be sharing the same slug.
I hope this helps! Let us know if you are still having any trouble with this, we’d be more than happy to assist you further.
