my theme option change has messed mu site's URL

Hello,

My web site is https://thepinecrestgroup.com/ and I am using “deep focus” theme by Elegant Themes for it. Everything was fine until, I changed something in theme options today.

In the theme options, I changed the “content area page” from “home” to another page called “contest”.

Now when I browse the site, it automatically redirects to https://thepinecrestgroup.com/contest/

I am clueless why.
I have changed back the content area page to “home” but still it doesnt help.

The featured slider on the home page doesnt work anymore. And the site automatically redirects to https://thepinecrestgroup.com/contest , instead of https://thepinecrestgroup.com/

I have set the content area back to “home” page. Also I ve also deleted “contest” page from site, but still the site automatically redirects to https://thepinecrestgroup.com/contest/ and says content not found. I am clueless. Please help me cos I didnt touch any other setting at all.

I will really appreciate your help.

Thank you!

Regards,
Mike
