I'm uploading a large CSV into my Magento back-end using the regular System > Import/Export > Import for products (14k rows). I've noticed that the page hangs on loading, I've left it for > 48 hours now but nothings changed - my products aren't updated. If I inspect what's going on in the browser page, I see the error http://test.mydomain.com/index.php/myadminpath/import/start/key/1234567890123/?form_key=12354678890 Failed to load from form.js
I had to change some settings in php.ini and flush the magento cache, and then upload in smaller batches. The CSV has to be in MS-DOS format also. I am still getting some errors for certain product lines but not others. It is very sensitive.. here are some posts I found that might help
