Slider images and Website Home Navigation are missing

Hi!

Just this morning when i logged in to our website, I found the Slider images are missing and also the Home navigation. Even I’m logged in to my dashboard, I can’t see the home Navigation (don’t know how you call it. The upper options in your website when you are log in.)

Your help will be highly appreciated. Thank you in advance.
