Salemaker not working in 1.5.8

I set up salemaker, but the status always shows red, or at best it enables briefly then off again, randomly... it's very odd... can't figure it out.

Any ideas?

Fixed this.

There are some problem when we add the staff picks.
Now, I have enabled all the category that are not coming under staffpicks, consignment, extras and clearance.
It works good.

Is there something that you learned or had to modify to make this work as expected? Ideally others could learn from the issue, make corrections to suit or determine that this thread doesn't apply to them...
