I was also unable to update pages, nothing happened and I couldn’t get a preview of any page adaptation.
I tried some more troubleshooting, so I updated the .htaccess with the data in the permalinks. I now get a message that updating pages failed, your probably offline and I still can’t get any preview.
In the .htaccess file I tried with HTTP and HTTPS, with the same result:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
