Unable to edit the solution in MATLAB Grader.

For a specific assignment in a MATLAB Grader course, some students experience an issue of not being able to edit their solution (i.e., the code present in the 'Function' text box).

The issue consistently happens for the same set of students, agnostic of the browser or OS. This issue only happens when the particular set of students try to edit the solution (code) for the particular set of assignment(s) inside the Function text box.

How can I resolve this issue?

The following workaround should resolve the issue for the affected students:

     1. Have the affected students navigate to the assignment(s)/problem(s) that are frozen (i.e., the assignment(s) for which they are not able to edit their code in the 'Function' text box).

     2. Now, select and copy any code they would like to save from the 'Function' text box.

     3. Finally, in the address bar of the browser, remove the trailing "?based_on=xxxxx" from the URL (i.e., from the end of the URL) and press enter.

         For example, the following URL:

         https://grader.mathworks.com/courses/9221-cs-109/problems/121255-water-resource-by-country/solutions/new?based_on=12345678

         would become:

         https://grader.mathworks.com/courses/9221-cs-109/problems/121255-water-resource-by-country/solutions/new

     4. This should be done for each frozen problem and this should make the code in the 'Function' text box editable.

     5. The students can also use the code copied earlier (in step 1) to rebuild their solution.

The name of the code block will depend on if the problem is a script or function type problem.

• In script type problems, the code block is labeled "Script"
• In function type problems, the code block is labeled "Function"
