This is Robin--Dave is having problems submitting to the forum. When he types into the text box, it deletes his stuff when he presses the submit button????
So, I'm sending on what is happening. Dave is experiencing another problem. He's the only one here using the Achievements so we're thinking the problems are linked. (Our server went down unexpectedly the night before so that should be considered as well.) A problem set that was working this morning--students were happily submitting answers-- now have problems which are producting the following error. Also, the points in the "Worth" column for the broken problems do not show up. If I do a force reload on the page, the points show up for an instant and then disappear. I updated the file you suggested(ProblemSetDetail.pm, I think, is the file you meant.) and this problem persists.
Anyway, here is the error message from a broken problem.
Anerror occured while processing your request. For help, please send mail to thissite's webmaster ( webmaster@localhost ),including all of the following information as well as what what you were doingwhen the error occured.

Yes, with the new ProblemSetDetail.pm editing individual's problem sets seem to be working now--Thanks a bunch!
We've tried different browsers: IE, Foxfire and Chrome on Windows and Linux machines. A corrupt file is a possibility since the server went down unintentionally the day before. I tried a "git pull' in the folder were Problem.pm resides, but it said the content was up to date. Would github know if a file was corrupt?
I've looked through the problem sets in a couple of courses and Dave's section is the only one I can find the error occurring.
If it would help, Dave could make a login for you to his course.
