We suddenly got a problem with the widget in wordpress.
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 (  => Array ( [number] => -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.
