We have created one template named “Knowledge Base Template”, We are looking to submit this over ThemeForest but we want all your reviews over it to avoid the rejection and make a proper move to publish it.
This item is not ready yet for ThemeForest, you should make unique layouts and unique design.
To be honest, it is a very basic template, so if you submit it now it can be hard rejected,
You should add more content, try to make unique layouts, work on colors, contrast, and Typography.
I believe that you should work more on this item before the submission.
