pagination not working for search

Hi,
On our website, pagination does not work for the search feature.
For example when searching for “wds” from the sidebar…

The first page of results is fine:
https://benjaminfulford.net/?s=wds

But the second page is not ok and displays the second page of *all* of the articles: https://benjaminfulford.net/page/2/?s=wds

I think that the “s=wds” query is not being passed through for the second page.

For information we are using permalinks with the following Custom Structure.
/%year%/%monthnum%/%day%/%postname%/

With permalinks, I believe the URL for the second page should look something like this instead. This URL works ok and displays the second page of results:
https://benjaminfulford.net/search/wds/page/2/

The page I need help with: [log in to see the link]
