homepage redirecting to a page in wordpress. Please Help

Hi,
I have a wordpress installation.

I created an email-us page and then went to the homepage, which now redirects to /email-us/

i didn't set it to this.

I have checked settings > front page and it ISN'T set to static page.
I have tried deleting the page.

what might cause the homepage to redirect? possibly plugins or widgets?

for reference the url is http://www.gt-6.com/IV/

 

fixed. turned out that the plugin 'redirection' was activated.
