Fatal Error - Upload malfunction

Hello!
I'm trying to import an xls file to hikashop.
The file contains product information from another website.
I import the file using CVS option and selecting UTF-8 in the file charset.
After clicking upload, I get a fatal error: Fatal error: Cannot access property started with '\0' in /data/www/bukbuk.cz/www.bukbuk.cz/administrator/components/com_hikashop/helpers/import.php on line 298
I've checked out line 298 and found no errors.
Tried to upload same file on another joomla website, didn't work.
This happened with hikashop 2.1.1
After updating to 2.1.2, the error persisted, though the line changed from 298 to 300.
Fatal error: Cannot access property started with '\0' in /data/www/bukbuk.cz/www.bukbuk.cz/administrator/components/com_hikashop/helpers/import.php on line 300

Please help me solve this problem.

Not sure if this is it (had a similar issue when I started with Hikashop.

Import as CVS (not as XLS) .. and it is best to do it via Open Office (calc). Excel adds funny stuff.

To ensure you are importing heading row correctly, firstly export a product to see their format.

As a test, try re-importing that file to isolate any issue with it.

Paste you data into that Spreadsheet, save, then try importing that saved CSV.

Like sambob said, the best solution would be to export some existing products through a CSV file, and then fill this CSV file with your product's line that you want to import .
