Running on ver 1.4.3
When I want to send an invoice, I click on the option to “send email” - this brings up the email form with the little airplane send button. When I click that button I ALWAYS get a 503 error on first click. If I click again, the email is sent successfully.
I’ve checked my server error logs and there is nothing logged for this event.
Any ideas what I can do to fix this?
(Running on a LiteSpeed server if that makes any difference)
