Embed rtSocial code into Enfold template (now being 'hidden' by header bg)

Hi,

This relates to the question that I raised here:
https://kriesi.at/support/topic/embed-rtsocial-code-into-enfold-template/

The issue was resolved, but since I upgraded Enfold to the most recent version it’s thrown up an issue.
Basically, the rtsocial social icons that I placed in the top section are now hidden by the semi-transparent header background.

If I change:
.header_bg{ position: absolute;}
to:
.header_bg{ position: relative;} (for example)

the social icons can be seen – but the sticky top menu now breaks.

How do I go about getting both to work at the same time? I’m guessing that there might be a simple change to the header_bg I can make that will fix this issue?

Thanks,

Daniel
