Agree.
VisualCron is a wonderful and complicated piece of software. I like the willingness to refactor and the frequent update cycle. But too often objects stop working and need fixes after upgrades. Having more and more logic put into the program, upgrades become more and more risky. A more thorough upgrade testing would be much appreciated!
I might have overlooked some info in this particular case, but I would have saved some frustrating hours if ie. a pop up had told me, that SFTP connections with external certificate files needed some action, and that I was better off recreating my FTPS connections.
