David, excuseme because I could not do it until today that I´m building a new site.
Here it is where you can check it:
https://www.softwareoficial.com/contacto
In appearance > customization > colors > buttons I´ve set the primary color as orange and the hover color in that blue that you can see there. As I told you, what does not work is the main color so the hover color works perfect.
I´ll wait for your answer and if you neec credentials for the site, just let me know.
Thanks
