I've learned that help pages have at least three different URLs. E.g.

If volunteer hours are rejected, you might get a message with a link to

If you click your profile dropdown, select Help Desk, and search for 'session prep', clicking the first result takes you to

If you asked Fin a question where the response included a doc link, you'll get an intercom URL back, like

From the intercom URL, I don't observe any issues. But if using one of the URLs that do not include intercom, then multiple things are broken:

1) Typing 'prep' into the search page takes you to an error page (attached)

2) Clicking the 'All Collections' link takes you to an error page (attached)

The URLs that don't work are of the form https://schoolhouse.world/en?q=prep and https://schoolhouse.world/en. Adding 'faq/' before 'en' fixes both URLs.

Sometimes search does work from a page without intercom, e.g. if done from https://schoolhouse.world/faq/en. But if done from one of the non-intercom URLs listed above (and I have no reason to believe it's specific to those pages), it does not.

It appears to me that what gets you into a bad state is

1) Searching. Searching for a page, and navigating to it, makes the 'All Collections' link exclude 'faq' and also makes further searches navigate to a broken page without 'faq'.

2) Having a direct non-intercom link to a page. After directly navigating to such a link, 'All Collections' is broken and search does not work.

If you start at https://schoolhouse.world/faq/en and just navigate, without ever searching, I've seen no issues. The 'All Collections' link will include 'faq'. The first search will work. And actually search and navigation to search results work ok for me for a while, before eventually we lose 'faq' and search is broken. I didn't track down if there's a pattern that eventually causes search to fail.
