Magento调试(7)：无法在Gd2.php中发送标头

Question

2012年-10-31T10:49:49+00:00调试(7)：无法发送标头；头已在/home/happiniess/public_html/magento/includes/src/Varien_Image_Adapter_Gd2.php，第133行中发送

2012-10-31T10:49:49+00:00 DEBUG (7): HEADERS ALREADY SENT: <pre>[0] /home/happiniess/public_html/magento/includes/src/__default.php:17239

( 
[0] => Array 
( 
[name] => Content-Type 
[value] => text/html; charset=UTF-8 
[replace] => 
)

)

当我检查magento/lib/Varien/Image/Adapter/Gd2.php代码时

public function display()
    {
        header(\"Content-type: \".$this->getMimeType());
        call_user_func($this->_getCallback(\'output\'), $this->_imageHandler); // 133 line
    }

这不是个虫子吗？

谁能给出更多的提示，如何调试它？

我补充说: /app/code/core/Mage/Core/Controller/Response/Http.php

Mage::log('HEADERS ALREADY SENT: '.mageDebugBacktrace(true, true, true)); 

/lib/Zend/Controller/Response/Avact.php

Mage::Log('Cannot send headers; headers already sent in ' . $file . ', line ' . $line);

然后得到错误信息: /home/happiniess/public_html/magento/includes/src/Varien_Image_Adapter_Gd2.php，第133行

现在我不知道怎么解决了！

救命！

试一试这个错误

1. 禁用编译和删除缓存

我认为新添加的文件不算复杂
