Problem uploading products via excel files .
They upload fine for several files and then the site crashes on upload attempt :
No webpage was found for the web address: http://mysite.com/Admin/Product/ImportExcel
HTTP ERROR 404
I check the product list and some products made it but the images did not upload . Not all products made it to the list .
I tried re-uploading excel with just one of the products and I used one of the products
that uploaded successfully with its image and I just changed the SKU . Still won't upload the image .
So has nothing to do with the image .
I see in the logs :
"The property 'Id' on entity type 'EntityMapping' has a temporary value while attempting to change the entity's state to 'Unchanged'. Either set a permanent value explicitly or ensure that the database is configured to generate values for this property."
I can't tell if this is related as this log is from the other day when I was making the upload attempts but I don't know what time it was . Now when I make an upload attempt , the logs are not updated . Seems the logs are not updated right away ?
In the database , Product_Picture_Mapping was not updated .
