PS 9.0.0 (theme Hummingbird) order quantity, undifined

[Frits van Leeuwen]

Hello all,

In PrestaShop 9.0.0, using the theme Hummingbird, I see that products can be ordered directly from the category page. However, I also see that a quantity can be entered using the + and - buttons. Less than 1 isn't possible. That's fine. It would also be helpful if clicking the + button checked whether the quantity is actually in stock.
Perhaps it would be even better if the - and + buttons were disabled, as you can't specify a higher or lower quantity than the current stock level.

I see the same thing on the product page.

But on the product page, I encounter the following issue: when I try to increase the quantity from 1 to 2 using the + sign, I get a block above that says "undifined."

regards,

Frits van Leeuwen

It’s a known bug in the Hummingbird theme. Switch to the Classic theme for now, where the issue doesn’t appear, until an update fixes it.
 

In the last monthly webinar they said by the end of September a new them version will be available. And I guess most issues will ve solved.
