After upgrading my PC from Windows 7 to Windows 10, the CSS and Bootstrap styles applied to my HTML page disappeared. I continued to use the same browser and WAMP server that I had used on Windows 7, but the styling was lost. Is there a way to resolve this issue and make my program look the same as it did on Windows 7? I have also included a picture for reference.
