but when I click those item, it's link a error URL.

It's automatically add p before item name

If I remove the URL to
www.infoto.tw/index.php/%E5%88%86%E9%A1%...1%A8/product/400tmax

It's work fine.

I have check each category but only 黑白負片 have this problem.
Will you help me to fix this problem

Hi,

That's because the products name start with a number and you turned on the "remove category and product id from URLs".
The system has to add a p to avoid using the number as id of the product.
I would recommend to fill the "alias" field of your product with a name which doesn't start with a number.
That should avoid the problem.
