 * Sometimes at login or logout I got following warnings:
    Warning: html_entity_decode():
   charset `?’ not supported, assuming utf-8 in /home/www/wpvtad/wp-content/plugins/

 * Hi,
    I’m not sure why you are seeing the warnings but I think you should check
   your php.ini file and see what you have for the following setting:
 * **default_charset**

 * default_charset is set to UTF-8
 * I’ll try to make this warning easy to reproduce.

 * > charset `?’ not supported
 * The fact that the warning states “?” for charset and not “UTF-8” seems to suggest
   that it is not reading the configured value you mentioned (UTF-8).
 * Have you checked your server logs to see if there are other related errors which
   might give you more clues?

 * No log entries. I am using now a staging site: [https://wissentest.vtad.de](https://wissentest.vtad.de)
   
   but can not reproduce the error. So lets forget it 🙂
