If your experiencing difficulty removing categories from the admin cp here is a quickfix.
Edit File: ./include/admin/categories.php
Change line 409 from
```php
db_query(“UPDATE ?:$product_features SET categories_path = ?p”, fn_remove_from_set(‘categories_path’, $v));
```
To
```php
db_query(“UPDATE ?:product_features SET categories_path = ?p”, fn_remove_from_set(‘categories_path’, $v));
```
(remove the dollar sign) and you will now be able to delete categories.
Important Note This will only fix deleting by the red ‘X’ the DHTML drop down for bulk delete is not affected by this change.
