Sliding images don't work fine

-- url of the page with the problem -- : www.lacasettabio.it/negozio-online/piantine
-- HikaShop version -- : 2.3.3
-- Joomla version -- : 2.5.27

Hi,
i noticed an issue.
On this page:
www.lacasettabio.it/negozio-online/piantine
If you click on the third one product ( Piantine di peperoncino Bhut jolokia ghost chilli) you have the correct product.
But if you click to slide right with > button you have always the same product.

Hi,
here a screenshot

Hi,

That's potentially because of the category assignation.
If the first associated category redirect to another one with the same product and vice versa, it loop.
Please try to change the category ordering on that product page.

Hi,
all those products have just one category associated.
Here a screenshot

Hi,

Is that product the last one of the "Piantine" category ?
You can see that by filtering on the direct sub elements in the product listing in backend in the Piantine category.

We will need a ftp and backend access to see what's happening, you can provide it via private message or contact form, don't forget to give the url of that topic in the message.

Hi, the product is the third one.
I'm going to send you the admin access.

Hi,

I have received the backend access but I need too a ftp one

Hi,
Ok, done

Hi,

I am not able to connect via FTP, authentication failed.

I'm sorry, you're right!
I sent you a new private message.
Thanks

Hi,

The issue come from the alias of your product with the id "228" which should be displayed when pressing "next" button.
It's alias is the same than "piante-di-peperoncino-piccante-vendita-online" so when pressing next it come back to the same product.

Please change this alias, and it will be ok.

Yes,
now it works fine.
Thank you!
