Can’t parse Mashable RSS Feed

Why is it that another web based reader has no problems displaying the Mashable feed but your plugin can’t do it?

This is one example of several feeds that will not work with your plugin, although if you plug them into a web based reader they work fine.

Thgis: https://feeds.mashable.com/Mashable
works here:
https://www.netvibes.com/subscribe.php?url=http%3A%2F%2Ffeeds.mashable.com%2FMashable

but not in yours

I have several other feeds I would like to diaply with the same problem, yet I have many other feeds that do work. I can;t figure out why some jsut won’t work with your plugin.

Help?
