Hi feoconsulting,
I’m having the same problem, that i hope you resolved.
I’m also using a database outside WP, check if the request concern the outside database, and then display informations with header to 200. Otherwise i let WP do its job.
But can’t figure out how to change this title “Nothing found for …”
Did you find a way to solve this ?
It would be nice !
If anyone else knows how to do that …
Thanks for any help
