Page 2 not found errors

I have read that over the last 10 years people have magically gotten errors out of the blue when you try to scroll to the second page of posts for your blog. My client is now experiencing this problem. I have tried troubleshooting it based on suggestions from lots and lots of other posts on this topic, but nothing has helped. The category page 2’s work fine. It is simply the page 2 from the main blog that does not work.

I have read that this has something to do with permalinks but even if we switch back to the default the problems are there.

We are running 4.2.2. and the theme is flatsome.

Any ideas of what I can try to fix this?

Thanks in advance.
