Can you please check theme if they have layout options?
or you can also change min-width from css for ‘article’ tag classes and id which is <article id=”post-4″ class=”post-4 page type-page status-publish hentry”> in your page.
As for the width of the map, there is this in the map plugin:
Width: 100% (set to 100% for a responive map)
So it must be something in the Theme. I just have no idea what to look for and where.
