there is only display 'not issue yet' when i click the certificate link eventhough the student already take the quiz.can anyone help me solve the problem
This isn't a lot to go on, but I'm guessing that the problem is that the student hasn't clicked on the certificate yet to issue it - even though they are eligible. One solution would be to have the administrator login as the student and click on the certificate to generate it or just make sure to tell students they have to click on their certificates to get them.
there is other problem..when i create a certificate and click 'save and display', there is nothing on the screen. it should be a button to print the certificate right?
Have you made sure you have Adobe Reader or Adobe Acrobat installed? That will cause a blank screen. The certificate is displayed as a PDF file.
