… if you encounter this or a similar problem the easiest solution is to validate your feed.

To validate your RSS feed, simply go to http://feedvalidator.org/check.cgi?url=

Enter your Feed URL and hit enter. Now you know if the feed is valid or not. Most likely it is not. Write down the error line and find out what entry is causing the error. When you found the post you should remove any signs that might cause problems. In my case I had to remove the “&-sign”. Because HTML hex-codes normally start with the “&”-sign they are causing some problems sometimes.
