Hi,

I am using ZenCart 1.3.8.
I have customized it to use another distant database as a source of info for my products.

Each time there is a search, it checks if product model (a book ISBN)
is in my database and proceeds. If not, it uses the distant database to create a new product. Works fine.

I changed one PHP file to update my database, when a product is within, with info on the distant database (availability from my providers).

It bugged. So I took the .bak file and replaced the faulty PHP file.

It won't work. I am lost here. The PHP files are the same as before.

What could be wrong ?
