Update to 1.4.2 – disabled appearance functions

I just updated to the most recent version and the colors for my navigation have reverted back to the template colors. I am attempting to remove the template color and add the correct color to the stylesheet via editor but it is not working. Per the forum, to edit nav colors I should go to Appearance > Customize > Menus, but the Menus option is not even there anymore. Please advise.
Also, this site has had a couple instances recently of vulgar language appearing in the header – tagging onto the Site Title. Can you provide any insight on how / why that is happening. Is it at the hosting level?
Thank you!

Amy
