Hi there, @greentec,

Have you tried sending the invoice in a private window?

Private browsing prevents cookies from being stored on the computer, making it a great place to identify browser problems. Use any of these keyboard shortcuts depending on the browser you're using:

Google Chrome: press Ctrl + Shift + N  
Mozilla Firefox: press Ctrl + Shift + P
Internet Explorer: press Ctrl + Shift + P
Safari: press Command + Shift + N

Perform the steps in the Incognito window:

1. Create an invoice or open one you already created.
2. At the lower right, from the ▼ drop-down menu, select Save and send.
3. Make sure all the information in the email is correct.
4. Select Send and close.

If it works, clear the browser's cache to remove the history or log files so you can start with a clean slate.
