1. Date certificate granted When editing a certificate, there is a token: Certificate date [node:certificate_granted_node] The day the certificate was granted However, this token is not filled in like other ones such as: [node:title] and [current-date:custom:d-M-Y] both of which work correctly. The certificate just displays [node:certificate_granted_node] We want to display the date the certificate was granted and not the current date. 2. Certificate text from tokens problem Because the site has content in 3 languages, there are 3 certificates. However, the tokens display a series of questions marks rather than text. Is this a problem with the HTML to PDF or something else? We are using dompdf. profiles/opigno_lms/libraries/dompdf/dompdf_config.inc.php We tried to install wkhtmltopdf using your instructions in the Opigno manual but it does not work on our site. sites/all/libraries/wkhtmltopdf/wkhtmltopdf We have complete control of the server so can make any setups needed. How can we troubleshoot this?
