As BRGiff said, that did the trick. Thanks for pointing out the solution.
I stopped upgrading because 1.48 was doing everything I needed just fine. (If it isn't broken, don't fix it
)
A nice new feature (assuming you need any ideas) would be an option to send an email to a separate email address when a scheduled recipe fails. For example, I'm usually a few days behind in reading USA Today on my Paperwhite, and Calibre runs on a computer I just use to run scheduled jobs. By the time I notice a recipe failed, it's sometimes too late to go back to run it. The issue could be as simple as the site was down for a few hours and all I need to do is manually run the recipe.
