On the attempt to open httpdocs folder in Customer Control Panel > Websites & Domains > File Manager I get "Internal Error".

The /var/log/sw-cp-server/error_log shows the following error:

    (mod_fastcgi.c.2746) FastCGI-stderr: PHP Warning: json_encode(): Invalid UTF-8 sequence in argument; File: /usr/local/psa/admin/plib/Service/Agent/Transport/JsonRpc.php, Line: 446


The folder you are tying to open includes files that have names with non-UTF symbols.


  1. Login to the service node with the subscription in question.

  2. Run the following command to find a file with non-UTF symbols:

    #ls -laR /var/www/vhosts/ | grep --color='auto' -P -n "[\x80-\xFF]"

    The output will show files with non-UTF symbols in the name, for example:

    # ls -laR /var/www/vhosts/ | grep --color='auto' -P -n "[\x80-\xFF]"
    -rw-r--r--  1 root root    0 Oct 16 22:59 ▒▒▒▒▒y▒}▒u▒▒.▒y▒}▒u▒~▒y
  3. Rename these files:

    # mv /var/www/vhosts/▒▒▒▒▒y▒\}▒u▒▒.▒y▒\}▒u▒~▒y <new file name>
