Question

我已经按照通常会解决此问题的必要步骤进行操作：

然而，我一直得到类似的结果。我相信我已成功实例化了类和辅助数据。有人能告诉我我在俯瞰什么吗？另外，system.xml文件可以出错吗？

更新：这只发生在view.phtml（产品详细信息页面）中，并且我认为对帮助主题的引用是错误的：

$ibtheme = $this->helper('ibtheme');

错误：

Answer 1

config.xml之前<?xml version="1.0"?>的开头有一些空格很可能这使得它无效并且没有加载到Magento的完整配置中删除空格，并确保xml有效。完成后清除缓存。

未来的小提示：始终使用错误报告和显示错误进行开发。同时设置开发人员模式可以帮助我们找到这些问题。
