Drupal 7.x

I've had google reCAPTCHA working on a website for a while. I recently got a notice that drupal 7 needed an update so I tried to log in to update. The reCAPTCHA box on the login form just says "ERROR for site owner: Invalid domain for site key". So...why? It was ok. Since I can't validate the reCAPTCHA I can't log in so I can't adjust the key, can I?

I opened a bug on this issue, but under a time crunch... doesn't look like anyone is maintaining recently, so would greatly appreciate a help hand from someone with an odd I face with the SimpleCorp 7.x-1.1 theme.

I have noticed that someone, somehow, has created their own account on my website. They created a user account called Alex and a Administrator account named Hannibal.

I have deleted the Hannibal account but it won't let me delete Alex because it doesn't have a valid email address. I have tried adding an email address so I can delete the account but that doesn't work.

How else could I remove the account?

In doing server housecleaning, I backed everything up and deleted stuff I (thought I) didn't need. Of course, Murphy's law, I zapped a Database and User for one I wanted. 

Not a big deal, I have a backup. 

So, since I didn't want that particular site on that server anyhow, I restored all of its files to the server where I wanted it, I restored the database and created the user based on the settings.php file, went to access the site and...

Can anyone suggest examples of Drupal-powered sites which successfully use a Commerce module with a vertical progress indicator/tracker, especially on mobile view?

Thanks, Colin
