After a student completes their course, they are given the option to download their certificate. However when you click on it, you are given a message "Something went wrong." and you are not able to download the certificate. Everything is up-to-date and already tried running the default template to see if that fixed it and no luck. However I should say you can see the Preview when you're customizing the certificate. Also should note I tried using the basic coursepress one too and no luck either.
