Ok.
I found solution to problem 1 which proves that you have not done any testing prior to releasing your templates.
in bootstrap.min.css you have css for modal class with prevents the k2 edit link to be shown.
Just removed this class and it is working now. I don't know if this will have any implications anywhere.
modal{position:fixed;top:0;right:0;bottom:0;left:0;z-index:1050;display:none;overflow:hidden;-webkit-overflow-scrolling:touch;outline:0}
Problem 2 still remains unanswered.
Don't you people care of keeping your existing customers and make your templates work?
I'm really surprised by this attitude. Unless you are not here to stay.
