i’ve run into an odd situation – wordpress was working just fine yet the new / Gutenberg editor did not save anything. No errors, but also no content saved – the only thing that was left was ‘Auto Draft’ with an empty content.
i’ve tracked it down to fact that .htaccess was not actually used and instead apache2 relied on ages old entry: ErrorDocument 404 /b/index.php
i’ve removed that entry, added:
<Directory /some/path/to/wordpress> AllowOverride All </Directory>
then restarted apache2 and it suddenly started to work!
