Hard rejected - we found it isn't at the quality standard required to move forward.

I uploaded a topic and it was rejected from Envato:
“Thank you for your submission. We have completed our review of “Belleza - Fashion Shopify 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.”
Could you please let us know of bugs or quality issues for which our topic is rejected? We will fix and avoid these problems in the future.
