Warn message in log “Invalid arguement supplied for foreach()”

  • Hello

    Using v 1.4.4 and I notice a lot of Warn message in the log file similar to this:

    [Tue Jan 31 12:45:36 2017] [warn] [client 58.108.174.105] mod_fcgid: stderr: PHP Warning: Invalid argument supplied for foreach() in ../htdocs/wp-content/plugins/head-cleaner/head-cleaner.php on line 2895, referer: https://www.xxxxxxx.org/wp-admin/update-core.php?action=do-plugin-upgrade

    [Tue Jan 31 12:37:56 2017] [warn] [client 157.55.39.189] mod_fcgid: stderr: PHP Warning: Invalid argument supplied for foreach() in ../htdocs/wp-content/plugins/head-cleaner/head-cleaner.php on line 2895

    Is this normal or does it indicate something that needs to be checked altered?

    Thanks
    Kerry
