Flexible Width Issues

Hello all –

I’m having a bit of trouble implementing the full width page template in my Bota theme WordPress site. I recently took over this site from another admin who left the site riddled with errors. I’ve managed to fix all of the errors he created except for the page width still appears off-center. I’ve deleted (and saved) the sidebar template and have checked all code in the stylesheet.

Any help would be appreciated
