Archive links redirect to homepage

I had to turn off Rank Math SEO plugin, because all monthly archive links (i.c. /2020/12/ or /2017/08/ etc.) made a 301 permanent redirect to the homepage.

Couldn’t figure out what caused the problem, but Dr. Google learned me that Yoast SEO – which I don’t use – was causing this same issue in the past. So I turned off Rank Math SEO to see if it was, turned out it did.

I do use a lot of other plugins also (incl. Redirection), so there probably could be a conflict between Rank Math with another plugin. Deactivating Redirection did not solve the issue.

I also tried database tools and rollback to earlier versions. For now I’m leaving Rank Math deactivated. My (large) website is on a VPS using Plesk. I just mention it, in case it could be related.
