Hello comunity,
I'm writing here with a big problem we're facing with our Prestashop 1.6.1.9 version. We've been using Advanced Stock Management successfully for ome while, and all was fine untill some weeks ago, when all of a sudden it seems that the quantity of the products we seell is not the same in Advanced Stock Management when comparing with the quantity available in Product/Quantities, after any kind of order placed by our customers. This obviously is very wrong, and when you have only one product on stock, it is ordered, but not correctly updated in Product Quantity, it allows other users to order it, when we actually don't have it anymore in stock.
The problem is like this: after each order, it seems that the quantity of the products is correctly updated in the advanced stock management, but not in product quantities. It seems random... and is happening for some products, but is very annoying and uncertain, as after each order we have to check manaully if the product was taken out of stock correctly... and sometime it causes inconsistencies...
Somehow it seems a syncronization issue, because to sync them we manually search the product that was not updated correctly, go on the Catalog -> Products -> Quantities and first select "I want to specify available quantities manually." and unckeck "I want to use the advanced stock management system for this product.", then Save. After this operation to turn back Advanced Stock Management for the mentioned product we check again "I want to use the advanced stock management system for this product." and also "The available quantities for the current product and its combinations are based on the stock in your warehouse (using the advanced stock management system)."
After this,the problem MIRACULOSELY dissapearas, and product quantity is synced correctly, appearing the same as in Advanced Stock Management.
As you can imagine this is extremely unpleasant as it is consuming a lot of time, and it might leave room for human errors...
Tried to clear cache several times, moved even to mysql and not on disk, worked for a while and then appeared again....
Please, did somenone experienced this? Searched through Google, but couldn't find anything related to this topic.
We're becoming desperate here, any help / idea would be much appreciated.
Thank you in advance,
Alex
