screenshot of error

WordPress has several such security holes. Try this one on your site: www.yourwebsite.com/?author=1 and you will see the name (replace the number to 2,3,4,5,6 and see all the usernames). AND #1 is ALWAYS the Admin. Go figure.

Hello, It is already displayed by WordPress in many place. Even many plugin shows username. So, I think there is nothing to worry about it.

Hello, Thanks for reporting, I just made a push to github  fix this issue.

What happened with you? Where’s demo, piture or any error examples?
