Division by zero erro when editing some products

-- url of the page with the problem -- : www.paintmaster.nl
-- HikaShop version -- : 4.5.1
-- Joomla version -- : 4.1.4
-- PHP version -- : 9.0.20
-- Browser(s) name and version -- : all browsers

Hi,

When editing some of my Hikashop-products a "division by zero" error occurs. See attachment for the stack trace and the screenshot of the product edit page.

Kind regards,
Peter

Hi again,
I discovered that it has to do something with using uppercase letters in the filename of a pdf, that is stored in media\com_hikashop\upload\safe
The filename contains uppercase letters. Changing it to lowercase the division by zero error is gone. The division by zero is on the location where the size of the file is computed, but the file can not be found zo it is divided by zero.

I don't know why this is happening now.

Regards,
Peter
