<sigh> You're not paying attention. The copyright text is in the language file. It's called in index.template.php by theme_copyright() function -
// Show the "Powered by" and "Valid" logos, as well as the copyright. Remember, the copyright must be somewhere!
echo '
<div id="footer_section"><div class="frame">
<ul class="reset">
<li class="copyright">', theme_copyright(), '</li>
<li><a id="button_xhtml" href="http://validator.w3.org/check?uri=referer" target="_blank" class="new_win" title="', $txt['valid_xhtml'], '"><span>', $txt['xhtml'], '</span></a></li>
', !empty($modSettings['xmlnews_enable']) && (!empty($modSettings['allow_guestAccess']) || $context['user']['is_logged']) ? '<li><a id="button_rss" href="' . $scripturl . '?action=.xml;type=rss" class="new_win"><span>' . $txt['rss'] . '</span></a></li>' : '', '
<li class="last"><a id="button_wap2" href="', $scripturl , '?wap2" class="new_win"><span>', $txt['wap2'], '</span></a></li>
</ul>';
// Show the load time?
Which is put together in Subs.php -
// Show the copyright...
function theme_copyright($get_it = false)
{
global $forum_copyright, $context, $boardurl, $forum_version, $txt, $modSettings;
// Don't display copyright for things like SSI.
if (!isset($forum_version))
return;
// Put in the version...
$forum_copyright = sprintf($forum_copyright, $forum_version);
echo '
<span class="smalltext" style="display: inline; visibility: visible; font-family: Verdana, Arial, sans-serif;">' . $forum_copyright . '
</span>';
}
The actual text is in the language file -
$forum_copyright = '<a href="' . $scripturl . '?action=credits" title="Simple Machines Forum" target="_blank" class="new_win">%1$s</a> |
<a href="http://www.simplemachines.org/about/smf/license.php" title="License" target="_blank" class="new_win">SMF © 2017</a>, <a href="http://www.simplemachines.org" title="Simple Machines" target="_blank" class="new_win">Simple Machines</a>';
Look in the language file for the duplicate code.
