Your modify does not work. You just asked me to replace it with exactly the same...
If it didnt work then we didnt have the same problem

I first tested theme offline and because .js file was not placed in the folder at the local level green login button didnt work. Also when i turned on HTTPS on my live server, browsers blocked that .js file because of the url starting with HTTP and not HTTPS in the html markup.
So maybe placing it localy could solve the problem of transition to HTTPS (this is a point to the author

)
I also changed breadcrumbs from this "/" to this "»" by modifying
bootstrap.css file in CSS folder of the theme.
To modify breadcrumbs separator in
bootstrap.css (in the
CSS folder of the theme) search this
/\00a0
Replace with (anything you like, or) this:
»
It should stay contained with "", for example "»"
Thanks to the author now i know that css had those crazy superpowers like creating the structure with ::before or ::after and the content property
