Theme Options resets the website!

Hi - Everytime I save something using "Theme Options" my entire website customisation is reset (feature slider, promotion headline, header slider etc) Now I stuck as I cannot change the promotion headline without accessing theme option. And Theme option will not save anything but will reset even what has been saved already! Please can you help? 1. Why can I not save anything via Theme Options? 2. Instead of saving why does everything get reset? 3. How can I change the Promotion headline if I don't use the theme option. I am sure this option was available on the wordpress menu under Appearance > customise but I can't see it any more. Please help - it is a live website but if any one goes their right now it looks under construction! www.successculture.com Thanks
