i own an affilaite store in wordpress. At the moment i have issues with uploading big files with over 10k products into my website. I'm using the WP all import at the moment but everytime i want to upload new products or when i want to delete a big batch i get a 500 error.
i need software which can upload CSV files into the website quickly. It would be nice if the software also deletes the out of stock / non excisting files automatically. I also need to track every out going click per partner shop. I need a system which can upload to 300k products. I'm planning to grow the website so i really need a good system.
the website is: [url removed, login to view]
