Advanced Stock Management Wreaking Havoc...

[EvilDragon]

I'm using PrestaShop 1.6.1.4. with 2 stores set up (multistore)

 

So far, I've used normal stock management and wanted to move to advanced stock management to handle all my supplies, etc. properly via PrestaShop.

 

However, enabling advanced stock management causes PrestaShop to do really weird things.

 

1. With some products, completing the purchase of a customer will lead into a neverending loading loop until the server times out with a 500 error. Debug shows nothing.

2. Editing products often does the same.

3. When I try to change a product from normal stock management to advanced stock management, it the shop also has a never-ending loading loop and sends thousands of "Product out of Stock"-eMails to my email account... it does that until I get the 500 error or cancel the process. The edited content is properly saved.

4. Often when editing a product, it deletes all price information of that product.

 

That only happens with advanced stock management enabled, if it's disabled, everything works fine.

Okay, fiddled around with it a bit more and found out when it does go wrong.

 

When a product exists in both shops, editing the product and ordering works fine.

 

When a product only exists in the SECOND shop, the following happens:

 

* When a customer places an order for that product, it hangs forever after the payment confirmation. The order is being created but lacks the product!

* When I try to edit that product, it hangs forever. Additionally, all prices are being deleted and it's being disabled.

 

Does anyone have an idea how to fix it?
