Hello to you all,
maybe one of you can give me advice.
I use the certificate function in moodle. Most of the participants use the app.
Now the app shows methe following Error:
Error
Call to undefined function mod_coursecertificate\outpu\external_format_text()
I already used a new template because I thought it has something to do with the upgrading to the new version, but the error still occurs.
Can somebody help me?
Kind regards
Greta
