Reported in the wild on https://ilsweb.cincinnatilibrary.org/collection-analysis/current_collection-3d4a4b7/bib?_facet=bib_level_callnumber - the "next page" link links to https://127.0.0.1:8010/collection-analysis/current_collection-3d4a4b7/bib?_facet=bib_level_callnumber&_next=100

That installation uses "base_url": "/collection-analysis/"

Weirdly all of the other links on that page - to facet results, sort orders, row permalinks etc - work fine. It's JUST the next_url one that is broken.

Also broken in their JSON: https://ilsweb.cincinnatilibrary.org/collection-analysis/current_collection-3d4a4b7/bib.json?_size=1 returns
