Search in category header appears on the sidebox with repeated categories

[mc12345678]

I think something wrong with the code in the includes/templates/your_template/sideboxes, but don't know how. Can you help?

Ideally this should be asked (after reviewing the thread) in the thread related to this plugin.

No guarantees, but it looks like if you change this portion:

                                $categories_query = "select c.categories_id, cd.categories_name, c.categories_status from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd  where c.categories_status='1' and parent_id = '0' and c.categories_id = cd.categories_id and cd.language_id = '" . (int)$_SESSION['languages_id'] . "' order by sort_order, cd.categories_name"; 

To:

                                $categories_query = "select DISTINCT c.categories_id, cd.categories_name, c.categories_status from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd  where c.categories_status='1' and parent_id = '0' and c.categories_id = cd.categories_id and cd.language_id = '" . (int)$_SESSION['languages_id'] . "' order by sort_order, cd.categories_name"; 

By adding DISTINCT to the query.

That the duplicates may be prevented.
