Could not retrieve title from feed.

此问题是由于对配置选项不熟悉造成的。

文中提到了导入CSVf时出现的错误，在12楼 francis55 提到了：

Yes, I had the same error message, and setting the "Attached to content type" in Basic settings to "Use standalone form" solved the problem.

A message for the designers of this very useful module: offering a
list of content types at this "Basic" level is somewhat confusing because you automatically believe you are choosing the output type of the feed - which is the selection you expect to have to make. Actually this happens in Processor - Node processor - settings,
which is much lower down in the interface.

就是讲要在Feed的基本设置页面把“Attached to Content type "的设置为”use standalone form"使用独立表单来操作。
