I think Bug 853662 may need to be backported as the problem with the images not being created is partly due to the compatibility of newer OS and the pear graphing library.
If we can backport the js graph stuff it would take care of the need to generate graph images (using GD) at all. -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.

The failure means that the statistic graphics are not generated.
