Menu Bootstrap - Not Responding to Clicks on Phones

Question

I'm using Bootstrap (last version 3.4.4) as my responsive framework. Also I am using jQuery v1.11.0.

My site is working ok in computers (Safari, Firefox, Chrome, IE), however when I try to open my site on phones, the responsive menu is not working. I can see the menu, the menu is collapsing ok, but when I click an option menu is not doing anything. The link doesn´t move to the selected option.

Its working ok in iPad and in some Android Phones, but in most of them is not working. I have tried in iPhone 4, 5, 6, and in BQ E5, BQ E6.

I researched a lot, I've tried different versions of Bootstrap, but cant find the solution to my problem. I hope you can help me.

My site is: http://mobile.solucionlegal.es/web/

And this is my script code:
