Problems after giving wordpress it's own directory

Hi, I have some issues after installing WordPress in a separate folder instead of root.

I applied ‘Using a pre-existing subdirectory install‘ from Giving WordPress Its Own Directory – codex. I can see my website but there is some issues that I think are related but cannot resolve :

– No admin bar showing front end
– Themes are working but I tried to install a Coming soon plugin and only the coming soon page show even if I am logged in. I should be able to see the site while non logged in user should see the coming soon page.

In root .htaccess looks like this :

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

and index.php looks like this :

define(‘WP_USE_THEMES’, true);
require( dirname( __FILE__ ) . ‘/folder/wp-blog-header.php’ );

Any ideas? Thanks.
