content modules giving fatal errors

whenever i publish a HikaShop Content Module i get a fatal error.
ive gone through the tutorials step by step for creating a category listing module or a menu listing of products but i keep recieving the same error


Fatal error: Call to undefined method hikashopProductClass::addAlias() in /hermes/waloraweb006/b1475/moo.swop09/2013/components/com_hikashop/views/product/view.html.php on line 538

Joomla! 2.5.9
hika shop 2.0

tank you

Hi,

Did you modified a file of the HikaShop core ?
The HikaShop product class (administrator/components/com_hikashop/classes/product.php) contains the function "addAlias" so the error should exists.

Please check that your class product file has not been modified and that it has the right version.
If you still have some problem, you can download and install HikaShop 2.1.0 in order to update all of your files.

Regards,
