The project tag button does not appear as stated. I check the invoice template and there is no warning message that would suggest it’s an old template as per instructions given elsewhere. I still can’t get the invoice CSS template options either. That was identified as a pop-up button that was not appearing in Firefox ( verison 27.0.1). Is there some environmental compatibility issue here?
I checked your account ending in 0023 although there are no sales invoices here I checked on a purchase invoice and it came up fine (Note: you need to hover your mouse over the invoice for it to appear):
I also checked with Firefox, no issues.
The CSS template editor won’t come up unless you have a sales invoices saved on your account.
