Wdiget problem

Hi all

We suddenly got a problem with the widget in wordpress.

The page take a very long time to load and in the page none of the javascripts works.

A PHP expert (not WP-expert) took a look at it and found that the page somehow ‘time-out’ in the widgets.php (mysite\wp-admin\includes\widgets.php).
Line 192 :

$has_form = call_user_func_array( $control['callback'], $control['params'] );

the call_user_func_array() call the following :

[callback] => widget_logic_extra_control
    [params] => Array
        (
            [0] => Array
                (
                    [number] => -1
                )

            [1] => jr_125ads-1
        )

Look like the fact that the fact that the parameter is -1 is the problem.

However what should we do ?

Turn [number] => -1 to [number] => 1 ?
Something else ?

Thank you in advance for your help.
