Default Wordpress can't be accessed - Downloads file on page load instead

[Damo]

I have recorded a short clip of my settings https://gyazo.com/bb81dc948393e5be363897634084bc0b

I have .htaccess with

# 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>
# END WordPress

What could be wrong? I think it's a php issue but I can't see what to set

Is this LiteSpeed Enterprise or OpenLiteSpeed?

If it downloads the PHP instead of loading it, check your PHP handler. Depending on the environment, you may need to set it at extapp: https://docs.litespeedtech.com/lsws/extapp/php/getting_started/
