$input['link_tag_end'] = form::get_text('link_tag_end', $cfg['link_tag_end'], '', 'required="required" lay-verify="required"');

修改为

$input['link_tag_end'] = form::get_text('link_tag_end', $cfg['link_tag_end']);

继续搜索

if(empty($link_tag_end)) E(1, lang('link_tag_end_not_empty'));

修改为

//if(empty($link_tag_end)) E(1, lang('link_tag_end_not_empty'));

// 标签URL---------最终统一返回 mid和 name

中间代码是标签路由

// 评论URL
