 * Just noticed that when saving network settings I get this error in some fields
 * O:8:”WP_Error”:2:{s:6:”errors”;a:1:{s:30:”wpdb_get_table_charset_failure”;a:1:{
   i:0;s:0:””;}}s:10:”error_data”;a:0:{}}
 * They are coming in reserved names, banned emails, banned domains. Anyone got 
   this problem? I can I solve it?
 * I’m using both wp and shardb latest

 * I’ve been trying to debug this and when I set debug to true the result is
 * SharDB must set a database connection for use with escaping
 * and at the input field
 * notice: Array to string conversion

 * I’m still trying to debug this, it seems that has to do with query function in
   db class. Found out that there are other problems when trying to create a new
   article and page with debug on, it gives undefined property for different variables.

 * Ron almost everything works perfect, I get correct information from the tables,
   but now when I update the network settings instead of appearing the illegal names
   gives me array() array() and if I turn on debug it shows different notices in
   settings page and at create article/page. So I don’t think as to do with that
   situation.
