Is there a way to check in the dashboard if I am using a separate installation or WordPress.com?

I Googled this for you and found this:

How Do I Know If I Have WordPress .Com Or .Org?

  1. Go to your WordPress login dashboard by typing your site’s domain into a browser followed by /wp-login.php

  2. Your WordPress login dashboard will appear. Hover your mouse over the WordPress logo in the center (or your own logo if you customized it).

  3. & Voila, the bottom left corner of the browser will tell you if you have wordpress.org or wordpress.com installed!

Basically:

  • if the link is not available or does not work – you are using wp.com

Update – I added a screen grab of wordpress.com login – note also the URL https://wordpress.com/log-in
