I was wrong…
The permalink setting is back to ‘Plain’.
If I try to change it to ‘Post name’ and save, it reverts back to ‘Plain’.
The value in wp_options in the database show /%postname%/
My URLs display as https://***.***.com/?page_id=21
So I am at a loss…
I am trying to change the permalink as recommended by Yoast SEO.
The problem may have been caused by the W3 Total Cache changes.
I commented out the following line and it seems to now work correctly.
rewrite ^/wp-content/cache/minify/ /index.php last;
Is this solution recommended?
Thanks
