I deactivated every plugin.
If rankMath 16 is activated, pages do not load, other than the front page.
If RankMath is deactivated, it works.
If I toggle RankMath on and off, the pages/posts fail and work, in line with that, with nothing else changed, so it must be RM 16
The theme has not been updated since December 31st.
So the only thing different is RankMath 16
I retrieved a copy of v15 and it works perfectly.
Does 16 depend on anything in Wordpress V5 ? - I am on 4.9
- I doubt it because my other sites, that don't use the TagDiv Newspaper these are working OK.
But none of those other site use RankMath redirection or some other RankMath features.
It looks like you changed some of the redirection code in V16
