Convert H2 to H1 Headings in joomla 2.5.4 - Joomla! Forum - community, help and support

hello in community.

i'd on following problems:
(the template used teamspirit , joomla version 2.5.4)

1) turn titles (articles, categories, featured etc) h2 heading h1.
i changed in \ templates \ xxxxxxx \ html \ com_content \ article default.php code

code: select all

<? php if ($ params-> ('show_title') | | $ params-> ('access-edit')):?> <h2 class = "item-page-title <? php echo $ this-> pageclass_sfx?> "> <? php if ($ params-> ('link_titles') &&! empty ($ this-> item-> readmore_link)):?> <a href =" <? php echo $ this-> item-> readmore_link;?> "> <? php echo $ this-> escape ($ this-> item-> title);?> </ a> <? php else:?> <? php echo $ this-> escape ($ this-> item-> title);?> php endif;?> </ h2><?php endif; ?>

from h2 h1 after each article page not show. similar happens when change h2 h1 in default.php in \ sitename \ components \ com_content \ views \ article \ tmpl


2) also, home page of site instead of displaying sitename title set in "global configuration", shows title of featured article (although had turned off , have set "show page heading = no") , after sitename title, .

can help?
thank in advance.

sometimes (in templates) there specific css code specific html tags. if change h2 h1, must change css wrote h2 h1!!!
it happens me, , when change css, h1 showing well.
