A few days ago I have installed SSL certificate and move to https. After this no one page (except homepage) was not abble to open. Each time I get an error The requested URL was not found on this server. Apache/2.4.18.After I pick in Settings -> Permalincs -> General -> Simple all started to work. But now I cant change permalinks from simple to something else because of error. Using plugin Really Simple SSL.

.htaccess (644 permission but I've tryed 777)

<IfModule mod_rewrite.c>RewriteEngine onRewriteCond %{HTTPS} !=on [NC]RewriteRule ^(.*)$ https://%{HTTP_HOST}%/$1 [R=301,L]</IfModule>RewriteEngine OnRewriteBase /RewriteRule ^index\.php$ - [L]RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule . /index.php [L]
