[OJ-AP] OnlineJudge Sandbox Error after updates

[Tom Hill]

My students are getting status error:
Internal Error (Sandbox error. Report to admin please.)
after update to 1.1.1

From 1.0, I copied 1.1. onlinejudge folder to ../mod/assignment/type

Logged in as admin.
went to ../admin/index.php

An sql table updated.

Next, copied 1.1.1 onlinejudge to same ../mod/assignment/type

When I logged in as admin no script ran.

To restore original function, I copied 1.0 onlinejudge folder back,
and 1.0 is working.

Sorry for the inconvenience.

Since 1.1.1 doesn't change the sandbox, the problem is a little weird.

First check your syslog. If it is the sandbox problem, there should be many "sand: ------------result code:255------------" in syslog. 

If no 255 code in syslog, check the permissions of onlinejudge/sandbox/sand and onlinejudge/languages/*.sh. They must be readable and executable to apache. 

The weird thing is that 1.1.1 uses these executable file in the same way with 1.0
