Hi Hikashop Support,

My product page at the back-end looks different from yours in the demo.
It looks like I don't have tabs for variants and also different buttons for upload image and add an image.
See: awesomescreenshot.com/0a159hr732

I already cleaned my cache but it seems to have no result.

I hope you can help me.

Kind regards,
Lumiga

Hi I found the solution.

At the system configuration / Display / CSS / Back-end CSS (was custom) and I select default now.

So that fixed the issue.

Sorry for my Topic.

Kind regards,
