<tr> <th scope="row" style="text-align:right; vertical-align:top;"> <label for="aiosp_disable"><?php _e('Disable on this page/post:', 'all_in_one_seo_pack')?></label> </th> <td> <input type="checkbox" name="aiosp_disable" id="aiosp_disable" <?php if ($aiosp_disable) echo "checked=\\"1\\""; ?>/> </td> </tr>

add_meta_box('aiosp',__('All in One SEO Pack', 'all_in_one_seo_pack'),'aiosp_meta','post'); add_meta_box('aiosp',__('All in One SEO Pack', 'all_in_one_seo_pack'),'aiosp_meta','page');

Generally, using "ucwords" on category titles is controversal – in other languages than English is NOT usually to have all first letters of titles uppercase.
