Navigation Bar and Footer consistency across the whole website

The current state of the website lacks consistency as there are so many pages present but almost all of them have a separate nav bar and footer which kills user experience and navigation and many nav bars and footer are not on theme of the website, lack buttons, layout issues etc which need to be fixed as soon as possible. I will be designing bot the nav bar and the footer from scratch making sure they do not have any layout issues and follow the design theme of the website.
