I’m having the same problem with the installation on your server, maybe I’m just going blond but it looks like the rewrite engine is not setup for me… I thought this was active by defualt when cpanel was installed but it does not seem so and I cannot seem to move forward on this.

I have even tested by adding a line in the .htaccess file:

RewriteEngine On

RewriteRule ^helloWorld/?$ /index.php [NC,L] <<<<<<!!!!!

RewriteBase /

RewriteRule ^index.php$ – [L]

Which should push the browser back to the index page if I enter https://mysite/helloworld if i’m not mistaken,

I however get an error "page not found".

I have removed the wordpress installation and installed a fresh wordpress site but still get the same error.

I have setup the subdomains wildcard as shown below:

Any idea what’s going on
