Students have tried submitting files in both the Assignment Activity, as well as to a Quiz question. Some (but not all) have started getting the error:
Exception syntax error, unexpected '\' (T_NS_SEPARATOR), expecting function (T_FUNCTION) or const (T_CONST)
Even as the admin, if I try to submit or add the file on their behalf, I get the same error. I can save the file to the feedback portion of the assignment, however.
Any ideas on I can resolve this? I've not come across this before but this has the potential to be quite irritating and problematic if students cannot simply submit assignments. It's hard to predict/reproduce since it has been fine to date and suddenly in the last couple of days this error has popped up (no, I haven't done any changes to the site or server settings).
Note: This is happening only in TWO classes (to my knowledge) that are nearly identical in structure and have groups (4 groups in each class) with some related restriction settings.
