URGENT! Limt reached - you can't add the product

Please turn on the debug mode of joomla in configuration of Joomla and try again. Then, if you get an error message report it to us so that we can give you more instructions.

Could you give a link to your website so that we can have a look ?

Did you personalize views ?
I don't think that it comes from options.

I looked at your website and I can add the product to the cart. It's just that it displays the error message because the option cannot be added since the quantity is 0. So it's actually normal and working as it should.

You can change the error message by editing the translation if you want:
www.hikashop.com/download/languages.html#modify

If you set a quantity in your options, the message won't appear.
If you still want to have no quantity but that you don't want to have the message, I'm afraid that the only solution is to modify the code in the file administrator/components/com_hikashop/classes/cart.php and remove the lines:

$app =& JFactory::getApplication();
if( $quantity == 0 ) {
$app->enqueueMessage( JText::sprintf( 'LIMIT_REACHED_REMOVED', $product->product_name));
} else {
$app->enqueueMessage( JText::sprintf( 'LIMIT_REACHED', $product->product_name));
}

It's not a bug.
Before, there was no error message when a product was added to the cart but that it couldn't be added because there was no stock.
Now there is an error message so that the user understand why his product is not in the cart.
So it's actually an improvement in that respect.
