Problem activating Better Backgrounds 3.0.7: call_user_func_array() warning

Hi,

Activating a copy of Better Backgrounds 3.0.7 installed today got a warning message…

—-
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘Custom_Background’ does not have a method ‘bbg_add_settings_link’ in /home/fairytal/public_html/wp-includes/plugin.php on line 170

…repeated three time in Plugins section when the plugin activated. Also, when it is activated, there are two ‘Background’ tabs available at ‘Appearance’ section of my custom theme (Hoon by press75.com).

Tend to think it is to do with a conflict over a Custom Background feature provided by the aforementioned theme.

Any coding solutions to fix it, friends? WordPress is not my strength at all.
