Background Manager Links not Working

I have been through the pages here and seen that many have the same problem as I do but not yet found a solution that works with my website.

I am able to add a background image with no plugin by using this custom code into the themes Custom CSS box:

{
background: url(https://www.velouk.net/wp-content/uploads/2013/02/2013_VeloUK_BackgroundImageR_05.gif) no-repeat top center; #000;
}

But what I need is the link for the background to work.

The website is: https://www.velouk.net/

The Background Manager plugin is great and I have managed to see a lot of the functions working but the key feature, that of a clickable background does not.

Have tried adding a normal url such as https://twitter.com/AussieLarry to the

Clickable Backgrounds is ticked in Settings.
The Background Image Link box has had the URL added in the settings for a ‘set’.

The site theme is Bold News by Woo Themes.
