Is there a way to check within the dashboard to know if I am using a separate installation or WordPress.com? I am working for a client and logged into their account and they themselves are not sure. Is there anything I can do to confirm or check?
I Googled this for you and found this:
How Do I Know If I Have WordPress .Com Or .Org?
Go to your WordPress login dashboard by typing your site’s domain into a browser followed by /wp-login.php
Your WordPress login dashboard will appear. Hover your mouse over the WordPress logo in the center (or your own logo if you customized it).
& Voila, the bottom left corner of the browser will tell you if you have wordpress.org or wordpress.com installed!
- 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
