Can't upload invoice template

[Robert]

Problem:  I'm getting the below error when trying to upload an invoice template.  I've checked and my file(InvoiceTemplateTest.DOC) is in Word 97 format.   What can be the problem?

Error: The Invoice Template must be Word 95/97 format

Answer: Your invoice template extension needs to be in all lower case.   Therefore, it should be from "InvoiceTemplateTest.DOC" to "InvoiceTemplateTest.doc"
