I spent a few hours reviewing this thread and I could not seem to find a solution for my issue.
I am unable to upload new products with new model numbers.
I can download files, modify them, and upload just fine. However if I download a file, strip all but 1 product out to keep it simple, then change the model number, when I try to upload it, it is saved in the temp directory fine (just like the others) but it will not insert it into the db. Nor do I get any errors in the box in the GUI. I have the /temp directory set to 777
I do have a lot of additional columns in both my products and products_description tables. All of which are mapped correctly in the easypopulate.php file. and are included when I download.
is there a way to determine where the code is failing? The fact that it will download and upload existing items makes it clear the configuration of the file is good.
