I want to set up a WordPress on Alibaba Cloud virtual host, but I have no trouble with the steps. When I open the temporary domain name, the following prompt pops up. I think it is a problem with the description of the directory? Please give me some advice. Warning: require(__DIR__/wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /data/home/bxu2442170501/htdocs/wordpress/index.php on line 17 Fatal error: require() [function.require]: Failed opening required '__DIR__/wp-blog-header.php' (include_path='.:/var/www/php5/lib/php') in /data/home/ bxu2442170501/htdocs/wordpress/index.php on line 17
