Made a site. Did LOT of changes. Used every customisation tool there is including site editor (beta)
Finally Added Query loop. Edited page. Made Post titles are links.
Fought with it about 2 hours yesterday. Didn’t work.
Today by chance, used Site Editor again. Query loop Post Title were **NOT** set as links.
Made the change. It worked.
If someone else has this experience, let’s sue wordpress to get our time back.
