I thought I'd post here before adding this to the bug tracker in hope someone is able to resolve this.
We have a Certificate set up that is dependent on grading 80% or above in a quiz. This has worked fine until we have upgraded the site to 1.9.5. Now when the student gets this grade or above they receive an internal server error on clicking to get the certificate. If they get lower than this grade, the page (exactly the same link) shows fine but says they need the required grades before receiving.
Could this be something to do with the gradebook changes in 1.9.5? Something not linking together properly...
Any help much appreciated!
