CHANGE BUTTONS COLORS

Hello,

I need to change the buttons colors of Ultimate Members plugin.

I have add the custom css code from the documentation (link below) and change the default colors with my colors. And Nothing Changed..

https://docs.ultimatemember.com/article/270-how-to-change-default-ultimate-member-blue-color-using-css

I tried editing CSS files manually with no result.

I started looking in plugin’s files and found variables (like primary_btn_color) and changed its value manually, and still nothing changed.

How can I change the colors of buttons?

Thanks in advance
