I have now done some tests, no one has succeeded, which is not so tragic. I thought later that it can not come alone from the German files and was right. I have deleted all German files from the server, the settings.pm adapted accordingly and they there, the error message comes also in the English language, even if it is standalone.

With
no warnings qw(redefine);
you can suppress the error message, but then I do not get much in the detailed version displayed, which is also not so important.
In principle I can with both lives because these information is not really important.
Now would have to know if this error message with you does not appear, which Perl modules (I think it is a Perl problem) with you are installed.
I have a usable script for this .. (appendix) (chmod 755)
Maybe (only if the error does not occur) I can update with appropriate module update the error and we then know what it is.
