PLEG logfile error

I am trying to enable logging (in standalone file). It used to work, but now the log window opens with this message:

Manual Scroll

File not found: /var/log/cmh/PLEG-221.logdata
File=FileSpec&Start=N&Grep=GrepSpec
Where FileSpec is relative to /tmp/log/cmh or a full spec.
N is # of Lines. If N from start else if -N from end.
GrepSepc is used to filter the file.

After you change the debug location … you need to restart Vera … then issue the Log command again.
