please help !!!
after using WebWork for another week without problems, now I am virtually shut down. I cannot use the Library Browser to add problems to any new Homework set I create. In Library Browser, I can create a new set but it will not let me add new problems. I gives the same error as before: instructorXMLHandle.error in a popup window. Once I click OK to kicks me out to the list of courses.
I have a homework 6 setup with 3 problems but I cannot add more.
The problem appeared when I tried to "move" problem before problem 2.
It did not do it and locked up the system.
I can use the file manager.
Students are responding questions in Homework 5 without problems.
I created Homework 7 but I cannot add a single problem to it.
What should I do?
