Magento错误：无法发送Collection.php中的标题错误

在我的Magento 1.6.2.0中，我在导出客户时出错：

a:5:{i:0;s:156:"Cannot send headers; headers already sent in .../Mage/Eav/Model/Resource/Entity/Attribute/Option/Collection.php, line 1";i:1;s:1385:"

保存新产品或编辑的产品后出现相同错误。产品已保存，但在出现错误之前：

无法发送标题；标题已发送

…表示存在标头重定向，但之前有输出。但在core/Mage/Eav/Model/Resource/Entity/Attribute/Option/Collection.php中，这到底在哪里

一些想法？谢谢。

找到了，它很愚蠢。我被这件事弄糊涂了

无法发送标题；标题已发送到…/Mage/Eav/Model/Resource/Entity/Attribute/Option/Collection.php，第1行

标题已发送到。。。第1行。这是文件的编码错误。因此，如果您正在使用notepadd++，请不要忘记将utf-8与BOM一起使用，这样可以节省您搜索有线错误的大量时间。

嗨，Stephan，您是否尝试过禁用所有自定义扩展？看起来有什么东西抛出了一个未正确捕获的错误，而Magento抛出了一个错误，因为在设置标题之前显示了一些数据，我禁用了所有扩展。还是一样的错误。我发现在更新搜索索引时也会出现同样的错误。
