After update specifications not work. On click on the button "Save" nothing happens.

Hello,
Can you :
- Active the Joomla debug mode ("Administration->Global configuration->System->Debug System/Language")
- Set the "error reporting" option of the Joomla configuration to "maximum"
- Test it again so that we can see if it display an error message which will help us to understand from what your issue is coming.
Thanks.

Do it. Byt on error display no messages.

Hi,

I've done a test with the admin account you provided and I was able to add a characteristic to my product and click on the validation button without any error:
monosnap.com/file/LiDaU89P1TsKvMm0HxcFbzZ6HP2Nsz

Characteristic add, it's right. But after i can't add options. Or what can i do after?

Hi,

You can't add options ?
The options are just below the characteristics, you can see it in the Nicolas' screenshot.
But if you're talking about the variants you have to go in the second tab in the product page ; to manage the variants.

Regards,

Second tab in the product page does not exist

Hello,
Can you download the last Hikashop version through our website, install it , and check that you correctly have a "Variants" tab a the top of your configuration page ?
Thanks.
