Email sending invoices

This worked fine until the latest update. It seems there is/are empty field(s)

Could you send HTML of your custom theme to bugs@manager.io ?

Hi Lubos
I discovered the error. When I upgraded it delete the email setting unbeknown to me. When I try to email the invoices the error occurred as seen in the image. By correcting the email setting and deleting the offending invoices it cleared the problem. After that new invoices were sent without problems

You must have been referring to an update of Windows, not an update of Manager. Is that correct?

Hi Lubos,
No, the latest version of Manager. Yes I have the latest version of Windows and I can’t say for sure which one caused the problem as I only use Manager a couple of times a month.

Cheers
