Item rejection?

Hi! I get this message and my item was not approved
I update it now and send it again, waiting for answer but that's not the problem now.

The reason was > Please include a working demo. Icon does not meet required dimensions.
How can I prove for MyBB themes like one demo working when the theme, templatwe ios ready ?

I am sorry to hear about the rejection.
All themes should have a working demo when they are submitted. You can change the icon and add a working demo link by editing the item and resubmitting the changes.

I submit the new changes like:

1.Was made a new LOGO 200x200 png/jpg
2.Was made video with working demo what you can found it in PREVIEW IMAGES + WORKING VIDEO DEMO.zip
3.Was updated Preview image with required dimension 1600x800.

" Please include a working demo. Icon does not meet required dimensions "


It's kind of dificult to add one good working demo after the template/theme is finished .
For mybb, all themes have the starting from default theme what I think you know, and you can't record like 20 - 50h hours of work, because generaly
1. You can't work 50h continuously
2. When you get a new idea, you try to make it fast and to add it because after maybe you can lose a good ideea.

Thank you and I hope you understand.



OFF:

I have more themes what I want to upload, but the system of uploading is a little bit complicated when i got this issues.
I found one topic here : https://www.codester.com/forum/topic/183/i-would-like-to-sell-mybb-themes
And i wanted to ask, if I can also buy one website domain for me and upload themes to have demo on my website and put also prices to sell on my website?

For themes we require the item to have a working demo, because hardly anybody purchases a theme if there is no real life example of the theme. Video does not seem to work.

a Demo is a working example of the theme. So an url where Mybb with the theme is installed.

If the demo has no links to purchase the item elsewhere it is no problem.

Thank you very much for your answer.
At the beginning I understand wrong what it means " WORKING DEMO " ... and I was thinking at steps of working with changes or how theme was made, what is kind of complicated to explain and to record all of this because it takes a lot of time.
All my themes will be updated soon and all will get live preview.

Respectful greetings and thank you for your time!
