Handheld footer bar not responding

Hello there,

I bought the plugin to change the ‘shopping’ footer bar because the buttons are white and the text in the searchbar is the wrong color but now the bar isn’t responding to the changes I made.

When you look at the shop from your mobile you’ll see my point.

Thank you in advance!

Greetings, Kor
