I think the error comes directly from the method exportAction() from Mage_ImportExport_Adminhtml_ExportController class:

public function exportAction()
    if ($this->getRequest()->getPost(Mage_ImportExport_Model_Export::FILTER_ELEMENT_GROUP)) {
        try {
            /** @var $model Mage_ImportExport_Model_Export */
            $model = Mage::getModel('importexport/export');

            return $this->_prepareDownloadResponse(
        } catch (Mage_Core_Exception $e) {
        } catch (Exception $e) {
            $this->_getSession()->addError($this->__('No valid data sent'));
    } else {
        $this->_getSession()->addError($this->__('No valid data sent'));
    return $this->_redirect('*/*/index');

So, check the var/log/exception.log, maybe you can see more information about the error.

  • there is no exception in exception log file,

  • and the path : Mage_ImportExport_Adminhtml_ExportController not in my root folder, its like app_code_core_mege_ImportExport (block,controllers,etc,helper,model,sql) thats all. How can i solve my error.
