This has been added into the Extra Footer HTML in the Theme options for the Bootstrap theme that you're using on your site.
To remove it, log in as admin, go the admin pages, Look & Feel, click the Options button next to Bootstrap theme, and remove the link from the Extra Footer HTML field.

Hi Joe
I don't all that several times to no avail. I keep getting an error message "Sorry, we found some problems with the information you entered. We've highlighted the relevant sections. Please check and resubmit".
There is nothing highlighted.

Interesting!
I just tried it on your site. The problem was that the Banner Image URL specified didn't exist, but you couldn't see the highlighted section because Show Top Banner was turned off.
Anyway, I removed this banner URL and could then save the settings fine, and the message in the footer has now gone!
Thanks
