Rejected again... My submission doesn’t meet CodeCanyons quality standards!

My WordPress plugin got rejected again (without telling a reason) the reviewer “found it isn’t at the quality standard required to move forward” and I’m confused now and don’t know what I can do to rise the quality of my Item.

Do they talk about the visuals or customization in the admin area, or maybe code-quality? how can I tell?
