Edited my civicrm.settings.php file to enable clean URL's (as described in https://docs.civicrm.org/sysadmin/en/latest/install/wordpress/) It does not work and any time I try to go to a clean URL page I get the standard wordpress "nothing found page"
Please check that you the base page here: https://example.org/wp-admin/admin.php?page=CiviCRM&q=civicrm/admin/setting/uf&reset=1
The value here
Should be an existing published WP Page.
I would then revisit the permalinks page.
That should 'fix' it.
