I'm afraid I did that, and when I visit the web interface to select saved searches, I get 404 errors on all of them. Regardless of what tags are used, what the virtual library is titled.
I've tried various tag combinations but they all fail, so I can't seem to isolate the issue.
Thanks for your help!
"Unknown error in saved search: tags"
But there are no symbols, just text in every title/tag.
There is something seriously wrong with saved searches, every single one is failing. Even from calibre GUI - not the web interface. They are getting saved wrong (tags) and that unknown error is the only message I'm seeing. No idea how to proceed now, sorry.
I am copying the search syntax exactly from how it's returned with an advanced search (which works just fine).
