Error when settings various system log settings from factory default config
Start with the factory default config. Go to System Logs, Firewall. Try to put some settings in the Manage Firewall Log section and save. You get:
Fatal error: Cannot unset string offsets in /usr/local/www/status_logs_filter.php on line 216
Similar if you go to DHCP or some other log and try to put specific settings in there and save.
After you go to the overall general system log settings page and make some choices and save, then the <syslog> section of the config gets some stuff in it and the error with specific log settings save no longer happens.
