Issue with 'available for order' in product PLS HELP

[Martin John]

Hi guys,

 

Im new to this forum. We started our project based on prestashop few weeks ago.

We are pretty happy so far but now we have this issue:

 

In 4 products I unchecked option available for order  because of a FB competition.

So these products temporary wouldnt be available for order. Now when this FB competition is over I would like to make them available for order again.

 

But when Im trying to enable option available for order its not possible to do so. I hit save button it looks like its OK but when I refresh the page and option available for order is unchecked again. 

 

I tried to uncheck and check this option again but nothing happened.

Also I tried to enable and disable Catalog mode but these 4 product are still not available for order

We are using prestashop 1.6.1.4 and advanced stock management

 

We are not able to sell these products again. Please any help highly appreciated

 

Thank you

Martin
