Product quantities not saved in backend

[cram1010]

I'm using Prestashop 1.5.5.0. When I go, in my backend, to Catalog->Products and, from there, to Quantities tab, any update I do to the quantity fields are not persisted when I click the Save button.

 

I tested it in a fresh Prestashop installation and I had the same problem.

 

Advanced stock management is not activated so the only available option, manually quantities, is checked.

 

Am I doing something wrong or is it a bug?

 

Thank you!

It's still happening in 1.5.6.0.

If you change only the quantity it doesn't save. If you also change any other field like description, than it will save the quantity.

That's strange.

 

Normally, when you update quantities from the Quantities tab of a product, you don't even need to click on Save: as soon as you enter a new number and cause the numeric field to lose focus (for example, by pressing Tab), the update is done via AJAX method (no page reloading) and a "Saved" popup message briefly appears and disappears on the top section of the page...
