Specify file location ERROR - File does not exist

-- url of the page with the problem -- : www.filkab.solar
-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1
-- PHP version -- : 7.0.0

Hi,
After upgrading Hikashop from 2.6.2 to 2.6.3, adding a file to a product by specifying file location doesn't work.
It constantly shows Error - File does not exists.
Even when I try to just re-save already added file it shows the same error. The file exists (i.e. images/datasheets/batteries....) and there is no problem downloading it from the front-end product page.

Hi,

We've added security checks to the file paths. So there must be a problem with the file paths you're using.
If you edit a file what do you have in the edition popup ? Could you do a screenshot ?
Make sure that the screenshot displays the full path or provide it so that we can look at it.

Hi nicolas,
Here are some of the file paths:

Hi,

You're supposed to write there the path from the upload secure folder root. By default it's in media/com_hikashop/upload/safe/
So please check the setting in the configuration, and then check that your files are in media/com_hikashop/upload/safe/images/datasheets/etc...
or adapt the upload secure folder setting to match what it is supposed to be.
