I'm stumped! Lots of sunshine, regular feeding and adequate water is all roses need to grow and bloom. Pruning encourages new growth and new flowers. I think I'd prune them back again to see if that prompts some flowering. We know your roses are capable of blooming so I wonder if they are getting more shade now than there were when you first planted them? Give them another haircut and see if that doesn't help. Knock Out roses bloom off and on during the summer months, usually resting after each flush of flowers so after pruning expect them to take 3-4 weeks to develop new stems, leaves and (hopefully) flower buds. Good luck with your roses!
