RSS Post Importer - Changing User Agent
Changing the User-Agent for the RSS Post Importer
Each time an RSS Feed is requested by a browser the browser must provide a User Agent signature to show what kind of device or browser wants to use the file or display it. Some servers block WordPress from making RSS requests. Should this happen it can be useful to change the User-agent.
Navigate to CM RSS Post Importer Pro → Options → Plugin Options
Find User Agent and select which of the User-Agent signature options you want to use. "Chrome on Windows" is a good choice.
Having made your choice, click on "Save Changes".
