I got impatient and just took it out. Did you figure out the map width?
I have a “page” that’s a section, and just added the short code for the google map to it, i.e. [map id=”1″ width=”100%” height=”500px”]
And in the extra style sheets, I set the container to 100% width as well:
#sidebar-after-main-secondary .container {width: 100% !important; padding: 0 !important}
