在OpenCart 2.0中安裝重寫的OpenCart 1.5模塊時出現500 Internal Server Error

Question

我需要在OpenCart 2上安裝與OpenCart 1.5兼容的模塊。安裝成功，但是出現以下錯誤：間接修改OpenCart。 我試圖在admin/controller/modules/mymodule.php重寫模塊的代碼。 應用以下代碼后，嘗試編輯模塊的設置時出現錯誤500。 可能出什么問題了，我在哪里弄錯了？

在根文件夾中打開index.php文件，並在最頂部添加以下代碼：

// Enables PHP error reporting
error_reporting(E_ALL);
ini_set('display_errors', 'On');

這將啟用完整的錯誤報告。 這也將顯示確切的錯誤和所涉及的代碼行。

如果無法從那里進行調試，請提供一些反饋並確保您包含錯誤消息。
