Reply To: Searching Problem
At present the site is in development behind a firewall so I cannot share it, though this should change next week as I bring it live but then a username and password will be needed.
However, what I have identified is that when a two word search is made the resulting URL is
…/forums/search/worda+wordb/
This produces the error.
However if I change the URL to
/forums/search/holding%20tank/
It then works so the code is inserting the wrong word separator.
This seems to have been quoted before https://bbpress.org/forums/topic/forum-search-form-widget-space-between-words-returns-a-404/
Though that was some years ago.
I have already tried a standard theme.
Does this provide any clues?
