Not working - Settings for Horizontal Carousel Slider

Hello, I have the latest download of OT Scroller Client Logos (and latest stable Joomla) installed.
The SETTINGS tab settings aren't working.
siliconstemacademy.com (homepage, right above footer section)

1. Settings: width not working
2. number of item: not working
3. durations / scrolling: not working

Months ago this was all working properly - now not scrolling, all logos showing at same time and displaying poorly (on all browsers).
Please help! Thank you

Hello, thanks for using our extensions!
I have seen the issue js on your site "TypeError: this.each is not a function" from bootstrap on media system
maybe the issue due conflict js when you update joomla.
Could you please send infor access to email: [email protected]
I'll check this
