Header Logo and Menu disappeared

Hello, I have read the posts but can not find a solution for this URL: vahorsecenter.org.

The site is built using the BB theme and BBPlugin Pro. Unfortunately, all the suggested fixes do not seem to work. I have deactivated all the plugins, reinstalled the theme and WP software.

Can you help resolve this problem. Visitors are not able to access any pages except the homepage.

Thanks,
Mary Murray
