Undefined offset: 0 notice

Hi
I get this notice when loading categories and sub categories at the bottom of the sidebar.
Notice: Undefined offset: 0 in /home/pcwar146/public_html/absclick.com/oc-content/themes/tatiana/search.php on line 194

The statement on line 194 shows:
$current_cat = $current_cat['0'];

any help, would be much appreciated.

Undefined notice does not represent errors, you should have notices notifications disabled on your hosting.
Fix is simple, replace line with:
$current_cat = isset($current_cat['0']) ? $current_cat['0'] : '';
