The working directory does not have write permissions. It belongs to the "root" (administrator) level user. Please, fix the directory/files owner and a group, not the write permissions.
System check
Attention! Apache web-server in FastCGI mode is recommended. If you use NGINX + PHP-FPM, make sure to add an additional rule to pass ALL requests for non-existing files and directories to /index.php.
Initial installation
