Hi, this is somewhat more advanced.
We can reach the website hp but not wp-admin or wp-login.php – always get a 404 not found.
We reinstalled the WP Files entirely, we checked the wp options table in the db, deleted every plugin and replaced the themes entirely (also deleted active plugins entries in options table in db). The dir and file permissions seem to be okay. Htaccess is a standard WordPress one. Added WP Debug into wp-config but no debug log gets created at all. When we run the maint repair.php it tells us to add the allow repair setting into wp-config but we did so before.
Running somewhat out of ideas… anyone came across this before?
