Is your modx installation using UTF-8? If you’re using another charset (e.g. ISO-8859-1), chances are there is some conversion going on behind the scenes, i.e. ß
Yes my modx installation using UTF-8. But der was no other chance in use ascii-code or other. But Only the view of the users (&type=`users`) have a problem with the "ß" there come a modx database error. Modx dont´t have a problem with them. When i look at the security/webuser page in the manager, there are all users correct, even theres with the ß. The error also must in the users database of webloginpe?
