In ATO it says we can create an archive but it is not working as you can see:

http://oneworldnow.net/archives/

It says: "Put the ID of an existing page into this field to make that page the Archives page."

I have no idea what to put in since my pages have name and not numbers.

What is the page id? Why is this not working?

Thanks in advance!

Go to "Pages" and look at the list of pages. Now hover over the page in question and you will see the id as part of the URL at the bottom of the page. It will say post=##

For more detailed info you can Google WordPress page id

Thanks so so much! That works...

Peace!
