It's telling you that on that line, $ids is not an array. As to why not, that would take some debugging to find out the call to wp_get_sidebars_widgets() is actually returning -- my guess is that it's returning Boolean false. You could try to debug with something like:

    public function getWidgets($position = null) {

        if (empty($this->widgets)) {
            $sideBarWidgets = wp_get_sidebar_widgets();
            foreach ($sideBarWidgets as $pos => $ids) {
                if( ! is_array($ids)) {
                    die("<pre>Not an array:\n".var_export($sideBarWidgets, true)."</pre>");
                }
                $this->widgets[$pos] = array();
                foreach ($ids as $id) {
                    $this->widgets[$pos][$id] = $this->get($id);
                }
            }
        } 

Or you could try contacting the theme creator, or see if there is a new version of the theme.

thanks for reply sir but now this error show

Fatal error: Call to undefined function wp_get_sidebar_widgets() in /home/semdr786/public_html/wp-content/themes/yoo_catalyst/warp/systems/wordpress.3.0/helpers/widgets.php on line 105

[NogDog]

That's because I made a typo, and "sidebars" should be plural.

[blacktiger786]

what do?

[blacktiger786]

please help me

[NogDog]

$sideBarWidgets = wp_get_sidebars_widgets();

[blacktiger786]

now show this

So, it looks like some elements are arrays and some are simple scalars with NULL values. I'm hesitant to suggest a final solution, since I don't really know what all this is supposed to do, nor how critical it is, but the simple solution to avoid the error might be something like:

    public function getWidgets($position = null) {

        if (empty($this->widgets)) {
            $sideBarWidgets = wp_get_sidebar_widgets();
            foreach ($sideBarWidgets as $pos => $ids) {
                if( ! is_array($ids)) {
                    continue; // just skip this item
                }
                $this->widgets[$pos] = array();
                foreach ($ids as $id) {
                    $this->widgets[$pos][$id] = $this->get($id);
                }
            }
        }
