Thank you for your submission. We have completed our review of “ zojne- Responsive, Multipurpose wordpress theme” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.

Here is the comment from your Envato Quality team reviewer:

Any incomplete, not prime-ready, low quality or not unique enough theme might be hard rejected. You are simply reserving the queue with an incomplete submission and creating a review delays. This applies to conversions as well!
