Hi everyone,
Our WeBWorK courses use GeoGebra in certain problems. However, since upgrading to WeBWorK version 2.18, these problems are no longer functioning.
Below is the error message for a specific problem.
We do have the AppletObjects.pl macro located in /opt/webwork/pg/macros.
Any insights or solutions would be greatly appreciated!
