Sage 9 Bootstrap 4.0.0-beta.2 modal not working

Hi, I am using Sage 9 with Bootstrap 4 beta 2, but have a problem with the modal not working, it works fine as an HTML page, does anyone know a reason why this might be ? Thanks

It’s difficult to troubleshoot without knowing whether you’re getting any javascript errors, and without seeing your code.

Hi, I fixed it now I switched back to alpha-6! Thanks
