I get an error pop up when I select a feed in the Feed Subscriptions pane. The error says:
Sorry, but an error occured: Index was outside of the bounds of the array.
This just started happening within the last two days and I have not upgraded or added any feeds lately.
It does not happen on all feed groups, and I am still able to access the feeds after I select a different feed and then reselect the feed that had the error.
