common.php
找到了555-565行，以前找的太不仔细了（languages/zh_cn/common.php）
$_LANG['p_y']['link_start'] = '<a href="http://www.ecshop.com" target="_blank" style=" font-family:Verdana; font-size:11px;color: #787676">';
$_LANG['p_y']['link_p'] = 'Powe';
$_LANG['p_y']['link_r'] = 'red ';
$_LANG['p_y']['link_b'] = 'by ';
$_LANG['p_y']['main_start'] = '<strong><span style="color: #787676">';
$_LANG['p_y']['main_e'] = 'E';
$_LANG['p_y']['main_c'] = 'CSho';
$_LANG['p_y']['main_p'] = 'p</span> ';
$_LANG['p_y']['v_s'] = '<span style="color: #787676">';
$_LANG['p_y']['v'] = VERSION;
$_LANG['p_y']['link_end'] = '</span></strong></a> ';红色部分是修改的地方
换成不明显的颜色或者与你网站比较搭配的颜色就可以了
