Background leading to the site can not log。
If you have administrative privileges php.ini，Then，Directly edit php.ini，The output_buffer open (just give a value of 1024-4086),If you do not have permission to php.ini，But the server provides the function of words .htaccess，Then in .htaccess add that this thing on it：
All the php files are checked still the same。
Finally found out that there was no host in php.ini setting output_buffering。Although not yet ask them to correct，But we can try to use .htaccess。
.htaccess set as follows：
php_value output_buffering 4096
Tested 。no problem。
