I am trying to change colours and font style from theme options but it doesn't work.

Your helpful suggestion would definitely be appreciated.
Can you explain your issue in more detail, please?
What font did you change, but it did not work?
Please check if you have Custom Skin set in Betheme -> Theme options -> Colors -> General. If this option is not selected, your changes in the Colors tab will not affect your website.
