Dear WPMU DEV Team,
When my users are logged into their PRO SITES account and request to
"Email a receipt copy for your last payment to: [email address] (change)"
they receive an TCPDF ERROR: [Image]
Searched in Pro Sites / Settings for area to modify invoice settings but was not able to find any
Would you please be so kind to share how to solve the TCPDF ERROR ?
Thank you so much
