Bootstrap modal: is not a function

Question

I have a modal in my page. When I try to call it when the windows load, it prints an error to the console that says :

$(...).modal is not a function
         


        

Answer 1

The problem is due to having jQuery instances more than one time. Take care if you are using many files with multiples instance of jQuery. Just leave 1 instance of jQuery and your code will work.
