Received Errors When Attempting To Preview Certificate in CoursePress

Ugh… I seem to be getting errors from everywhere. This time, as I was attempting to simply Preview the certificate in CoursePress, I received the errors below. Can you help resolve this matter? Thanks in advance.:

    Hello Sammy,

    I'm sorry to hear that those errors are showing on your site. Could you provide more information how I can replicate this issue on your site?

    I used support access and created test course on your site and then previewed certificate. It showed without any errors. Next I preview the certificate in settings of the CoursePress – that certificate also showed.

    kind regards,


Thank NAME, for their help.
