找到“ source/class/helper/helper_seo.php ”目录下的文件的38行~43行代码，如下：
- if($descriptiontext && (isset($_G['makehtml']) || CURSCRIPT == 'forum' || IS_ROBOT || $_G['adminid'] == 1)) {
- $seodescription = helper_seo::strreplace_strip_split($searchs, $replaces, $descriptiontext);
- }
- if($keywordstext && (isset($_G['makehtml']) || CURSCRIPT == 'forum' || IS_ROBOT || $_G['adminid'] == 1)) {
- $seokeywords = helper_seo::strreplace_strip_split($searchs, $replaces, $keywordstext);
- }
- if($descriptiontext) {
- $seodescription = helper_seo::strreplace_strip_split($searchs, $replaces, $descriptiontext);
- }
- if($keywordstext) {
- $seokeywords = helper_seo::strreplace_strip_split($searchs, $replaces, $keywordstext);
- }
