I've been using Magento for many years. When a customer orders something, I have the option to download an "official" invoice to print out. Normally I go to "Invoices," select the one I want, and choose "Print" in the top right corner. The invoice automatically downloads, I open it and print.
As of Monday, nothing downloads when I click on "print." The website just goes blank (white) and nothing happens.
How can I fix this?!
Thank you!
