Why can't I export my orders as usual?

I cannot export my orders as usual since 2 months ago. I followed the usual order export procedure but the exported file was blank with file name “login.html”

Hi @todayeveryday07

Unfortunately I do not know how you exported your orders so far. But if you are open to use a third party App, I may have a great solution for you! Our App DataChamp is a very easy to use tool which lets you automize your order exports. Our App is also very easy to set up but if you require any support, we can assist you of course! Hopefully we could help you with your concern and if you have any further questions, do not hesitate to contact us!

Actually I used the basic export function by clicking the “export” at the
shopify order list page. Unfortunately, the exported file is just a
"login.html, instead of the details of each order. May I know if I have
done anything wrong ?
