Why might the bootstrap modal window not work when everything is done according to the instructions?

Question

css

I'm trying to embed a modal window from bootstrap on the site, but it disappears as soon as it appears. can be viewed on the site
shaburakov.com/project/sportfresh/index.html
at the bottom of the button under the footer, all day trying to figure out why, nothing came to mind.
the window disappears as if the close button is immediately pressed, can anyone come across such a problem, help.

Answer 1

At a minimum, you need to disable duplicate js. You have bootstrap connected 2 times.

Answer 2

replace
with
$('#myModal').modal();
