[Ntop] enabling more detailed logs from UI bring ntopng to panic

[Luca Domenella]

hi folks,
to get an higher level of logging from Preferences menu of ntopng i enabled
more log files.
after that i restarted ntopng and it keeps crashing.
This is an extract of the messages:

is there a way to go back in the configuration ?
