DISCUZ更换域名，用以前的备份恢复后，出现错误提示

admin

Warning: is_file(): open_basedir restriction in effect. File(/www/wwwroot/8wf//source//class/discuz/discuz_application.php) is not within the allowed path(s): (/www/wwwroot/00077/:/tmp/) in /www/wwwroot/8wf/source/class/class_core.php on line 106

解决的方法是清理缓存目录，rm -rf /www/wwwroot/8wf/data/cache/*
将目录下所有文件删除，即可正常访问
