404 error after upgrade

[mfahl]

Just upgraded test board to 4.18.2

After a struggle i have got it working but when clicking log in i get following error

The requested URL /index.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

My .htaccess is
 

<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(jpeg|jpg|gif|png)$ /public/404.php [NC,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Any help much appreciated please.

Now sorted,chaged to correct .htaccess.
