I can see several information about invoice pdf not working but only reflects on lite version. I purchased EE4 but invoice is not working and it gives this error on my site:

Hi David,

I’m sorry you having trouble with the invoices, there are currently no known issues with the invoices in lite/decafe vs regular versions of Event Espresso.

I ran a test registration on your event, selected invoice and then tested downloading both the order confirmation and invoice with any problems. Is this happening on a specific event or within a specific location?
