Hi,
Please, after an order has been placed, WHMCS sends an Email with the PDF Invoice attached to the customer, when opening the PDF the invoice does not appear (the PDF file is delivered, but the page is blank), this problem also occurs in Adm area (blank page too). I contacted WHMCS Support, they analyzed it and found that the problem is in the CryptoCloud theme. To test I enabled the WHMCS default theme and everything went back to normal (the invoice is shown normally), when enabling the CryptoCloud Theme the same problem returns. I need your help.
Best Regards!
