[英]script works on wamp server but not on my vps
好吧，所以我正在做一个论坛项目，遇到了麻烦。 将我所有的文件上传到wamp中，并开始安装过程，一切正常。 但是，当我将相同文件上传到我的实时网站（使用whm和cpanel）时，我会经历安装过程，当我进入index_3.php并键入所有服务器信息时，我单击继续并出现白屏，没有错误。 我检查了php.ini并打开了显示错误，什么也没有。 检查了cpanel错误日志，什么都没有...
我的index_3.php文件：

这是我的index_4.php文件，在index_3.php之后变成白色：

我不知道您的代码如何在您的开发环境中工作。 PHP语法错误：
'; $write_config=f open( "../forum/db_config.php", "w"); fwrite($write_config, $config_file); fclose($write_config); } ?>
一定是
'; $write_config=fopen( "../forum/db_config.php", "w"); fwrite($write_config, $config_file); fclose($write_config); } ?>
（“ f”和“ open”之间没有空格）
无论如何：如果要调试此类错误，请确保已将error_reporting设置为E_ALL。 您可能还需要检查服务器错误日志。
