Hello,
i get the following error message in backend, when i open products:

Unknown format specifier " "

What the HELL is happening last time with this shop system? I have seen, that there is an update tu 6.2.0 available. i did this update.

then i was able to visit product page in backend.

i change the product quantity, and the product was destryed. a lot of parameters was undefined.

i could cry.

....

Hi,

You're the first one reporting an issue with the product edit page with the 6.2.0, so it's hard to provide a helpful answer.

Regarding the "Unknown format specifier " "" error, please activate the "debug system" setting of the Joomla configuration and try again. It should display an error message with more information about the issue. That will allow us to understand what's going on so that we can tell you what to do.

It's probable that the error you had before the update what the cause of the problem and that updating HikaShop didn't change anything to the problem and saving the product just made the problem worst with that product.
