Enable template path hint in admin Panel - Magento

There are two ways to enable admin panel path hints.

1.
You can enable template and block path hints in every store (including the admin store) by setting them in the Magento configuration. To do this, simply edit your module's configuration file app/etc/config.xml (which gets injected into Magento's global configuration).

To enable template and block path hints in the admin area add this to your app/etc/config.xml file

<config>

    ...

    <stores>
        <admin>
            <dev>
                <debug>
                    <template_hints>1</template_hints>
                    <template_hints_blocks>1</template_hints_blocks>
                </debug>
            </dev>
        </admin>
    </stores>
</config>

To disable path hints simply change to 0, or delete the node.

2.

You can do it by changing the database directly. If you have something like phpMyAdmin that is a good way to gain access. Enter this SQL.

INSERT INTO `core_config_data` (`scope`, `scope_id`, `path`, `value`)
       VALUES ('websites', '0', 'dev/debug/template_hints', '1');

When you are done with path hints just delete the matching record from core_config_data Or update the value field to 0 instead of deleting the whole record, it will probably be the last one since you've just added it.
