I installed the plugin on a totally clean install of WP 4.31 / Twenty Fifteen
I have these two bugs (so far)
DISABLE CONTACT FORM
I think there should be a button on checkbox there, but instead it is linked text that doesn't go anywhere. See attached jobs-tech1.png
Is this integration so you can charge for job listings? See attached jobs-tech2.png (the error might just be because MarketPress isn't installed?
