Not working on Course theme

There seems to be some kind of redirect there. I would investigate that: why does your admin-ajax URL return a 302 Found redirect? That’s unusual, and is likely breaking the search.

By the way, the automatic Finnish translation you’re using is terrible. It would be better to provide the site in English than use that translation.

Thanks for the suggestion. I have fixed anything that could possibly cause a redirect, but the issue isn’t resolved. I read here that Relevanssi has a conflict with Sensei LMS, which I’m using. Is this the reason for this issue? Has this conflict been fixed already?

No, because that’s a Relevanssi issue, and you’re using Relevanssi Live Ajax Search, which is a different product. In this case, the problem doesn’t even reach the search; it’s in the front-end layer.

This is something specific to your site: I tried installing Course on my test site, and the Live Ajax Search works without problems. So there’s nothing in the theme itself that would make it incompatible with the Live Ajax Search.

The Sensei LMS problem isn’t and cannot be fixed because Sensei is a premium product and I don’t have it. I don’t remember what the problem was; it was found out years ago.

I’m using both Relevanssi and Relevanssi Live Ajax Search. I’ll look into the issue, and see if I can fix it myself, else, I’ll sort for an alternative. Thanks so much for your help. I’ll take it from here.
