打开目录template\default\common下的header_common.htm文件，搜索：
<title><!–{if !empty($navtitle)}–>$navtitle – <!–{/if}–><!–{if empty($nobbname)}–>
$_G[‘setting’][‘bbname’] – <!–{/if}–> Powered by Discuz!</title>
修改为
<title><!–{if !empty($navtitle)}–>$navtitle<!–{/if}–><!–{if empty($nobbname)}–> –
$_G[‘setting’][‘bbname’]<!–{/if}–></title>
再修改文件：source\class\helper\helper_seo.php
查找：
public static function strreplace_strip_split($searchs, $replaces, $str) {
$searchspace = array(‘((\s*\-\s*)+)’, ‘((\s*\,\s*)+)’, ‘((\s*\|\s*)+)’, ‘((\s*\t\s*)
+)’, ‘((\s*_\s*)+)’);
$replacespace = array(‘-‘, ‘,’, ‘|’, ‘ ‘, ‘_’);
return trim(preg_replace($searchspace, $replacespace, str_replace($searchs, $replaces,
$str)), ‘ ,-|_’);
}
修改为
public static function strreplace_strip_split($searchs, $replaces, $str) {
$searchspace = array(‘(((\s)*\-(\s)*)+)’, ‘(((\s)*\,(\s)*)+)’, ‘(((\s)*\|(\s)*)+)’,
‘(((\s)*\t(\s)*)+)’, ‘(((\s)*_(\s)*)+)’);
$replacespace = array(‘$3-$3’, ‘$3,$3’, ‘$3|$3’, ‘$3 $3’, ‘$3_$3’);
return trim(preg_replace($searchspace, $replacespace, str_replace($searchs, $replaces,
$str)), ‘ ,-|_’);
}
