Discuz 安装完成后，后台打开Ucenter出现404 1. Discuz 安装完成后，后台打开Ucenter出现404：这是由于Ucenter获取UC_API参数不正确请求路径出错出现404的原因。 解决方法： 进入uc_server目录，分别编辑admin.php、avatar.php、index.php 注释下面一行代码、重新定义UC_API地址。//define('UC_API', strtolower((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on' ? 'https' : 'http').'://'.$_SERVER['HTTP_HOST'].substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/')))); define('UC_API', 'https://domain.com/bbs/uc_server');2. Ucenter打开后空白这是由于uc_server/data没有读取模板&数据权限的原因。解决方法： 进入uc_server目录，执行chmod -R 777 data;3.后台管理面板被锁解决方法：删除pre_common_admincp_session表中对应的UIDdelete from pre_common_admincp_session where uid = 1;
