.fb_iframe_widget {
background-color: #ffffff !important;
}
This is the correct “class” name.
I added it to the custom css code section of my theme, and it worked like a charm.
If you don’t have a custom css section, then you can install a plug in that provides this functionality.
In no case do you want to modify the theme core css files, or the plugin files, as if and when they upgrade, your changes will be lost forever.
If this doesn’t work, you should contact the theme developer or a free lance programmer for assistance.
