First, let me direct you to a QuickTip that has some tips for you when working with shortcodes that apply to any plugin that uses them:
To solve the issue you speak of…
Edit the page where you inserted the shortcode. I’m guessing you copy/pasted it or an option for it from the doc page into the WP Visual Editor which is why you’re redirected to my site.
Switch the post editor to the Text tab.
Now remove the link to my site from around or within the shortcode. While you at it. It probably is likely there are other HTML elements, not just the link, in and around the shortcode, remove all that you find.
Update the page.
That should solve the issue.
