Hi, During ISPConfig upgrade, I saw a lot of locale warning messages: perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = ""en_AR:en_US:en_GB:en"", LC_ALL = (unset), LANG = ""en_US"" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). How I can do to fix it? Thanks in advance Pablo
