I have an RSS feed which hasn't updated after the initial import, I actually managed to get it to update once using cron, but even that has since stopped working, looking at the original feed, I see it is being updated, I'm just not getting the updates on my site.

My feed importer settings are as follows:

• It is attached to a specific content type
• Minimum refresh period: 15 mins.
• Import on submission: checked
• Fetcher: HTTP
• Parser: common syndication parser
• Processor: node processor
• I respecify the content type in node processor settings
• Input format: default
• Expire nodes: never
• Update existing nodes: Update existing nodes (slower than replacing them)

Is there something else I need to do, maybe configure something in Job Scheduler? I couldn't find a UI for it...

Thanks!
