Suddently I cannot run any log:xxx commands. I alwys get follwoing errors:
openhab> log:tail
[Fatal Error] :124:36: Character reference "" is an invalid XML character.
Error executing command: Unable to retrieve level for logger
Somehow I destroyed something. has anybody an idea how I get this working again?
seems to be the apostrophe character ( see ' - Apostrophe (U+0027) - HTML Symbols ).
Did you edit the configuration files that define log levels and filters for logging ?
yes, it should work again.
I do not know if the change in the file is immediately detected or something need to be restarted but removing the entry should/must help.
