Hi,
after update to new version, the layout of the product edit/creation page is broken, it's only in one column and no tabs was be shown (see attachment). I can't find no solution. Can you help me please?
Thanks,
best regards

Hi,

It is possible that you have some CSS override for the HikaShop backend CSS file.
Please edit your HikaShop configuration in order to use the default HikaShop backend CSS file ; there you will have the new product edition interface.
Afterwards, you could see to re-integrate your backend CSS modifications into a new override, based on the latest HikaShop CSS file.

Regards,
