Can't set the width for page wrapper

I copied all php files as you suggested and it works fine for everything else except for page wrapper width. For some reason I can't set it wider than 584px and i need it to be 614px.I even went to original css in your plugins folder (when update arrive i will change it again) but that didn't help either.

Bellow is example taken from firebug. First width value always remains the same and other width values bellow that are crossed.

#qa-page-wrapper {
width: 584px;
}
#qa-page-wrapper {
float: left;
overflow: hidden;
padding-bottom: 2em;
width: 614px; (this has linethrough)
}
#qa-page-wrapper {
width: 614px;(this too)
}
#qa-page-wrapper {
background: none repeat scroll 0 0 #FFFFFF;
border-radius: 5px 5px 5px 5px;
box-shadow: 0 1px 3px rgba(0, 0, 0, 0.35);
margin-bottom: 30px;
margin-right: 70px;
width: 614px;(and this too)
}
