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(http://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: http://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.
