With regard to your color theme issue, do you recall what modifications you’ve made thus far that may have affected this?
You didn’t accidentally delete the green theme files, did you?
As for the “bar” within your footer, I believe this is the CSS controlling this element . . .
/templates/ja_business/css/template.css . . . at line 912
<blockquote>#ja-container .main {
background: url(../images/demo.gif) no-repeat center top #fff;
padding-bottom: 20px;
padding-top: 20px;
</blockquote>
remove the padding properties, so that it looks like this . . .
<blockquote>#ja-container .main {
background: url(../images/demo.gif) no-repeat center top #fff;
}
</blockquote>
SAVE CHANGES . . . CLEAR CACHE . . . REFRESH PAGE
Did that resolve the issue?
