error msg shows when create invoice and try to email but fail

Hi ChiefMouse, 

Thanks for your post. We've seen this error to appear when opening a pay item not emailing, so I can investigate this further can you retrieve the Chrome Console errors:

To open the console can be opened using one of these methods

• Select the Chrome menu (3 vertical dots) and choose More Tools >> Developer Tools
• Right click on the Chrome window and choose Inspect
• Using the shortcut keys Ctrl + Shift + I(nspect)

Once you've opened the console:

1. Choose the Console tab to view the logs being produced.
2. Right click and choose Clear Console
3. Please repeat the action that causes the error in your file. Any errors within the logs will be recorded in red error text.
4. You can save the log as a .TXT file and attach it to this thread or please attach a screenshot
