Highend theme issues

Hello

I am experiencing the following issues with the Highend theme.

1. I have used the customised options to change my site’s accent colour, the background colour of my navigation bar and navigation text. Unfortunately the changes are not updating to my site.

2. The text of the icon feature box is to dark for my black background. I have used this CSS code [.feature-box h4.bold { color: #FFFFFF; }] to change the title text, how can I update it to include the text as well.

3. I have used a button on my page (see my site link below), but the bottom portion of the button is missing. It is visible on my tablet – but not on my desktop.

3. The social icons are missing from the right widget in the top bar of my site. They are visible on my tablet, but not on my desktop.

My site is: http://www.locallinko.com/landing-page/

I look forward to hearing from you.
