The download link doesn't yield any download.

The fault is repeatable - it is not possible to disable syslog.

However, it is possible to make and successfully submit other changes - for example port and protocol can be updated and committed. It is only the attempt to disable syslog that causes the crash.

What did you expect to happen?

Syslog should be disabled. No more. No less.

How to reproduce it (minimal and precise)

1. Got to settings
2. Got to Advanced
3. Scroll down to syslog
4. Set to disabled
5. Scroll down to submit and click
6. System generates error.
