$core_config[‘db’][‘type’] = ‘mysqli’; // database engine

Mysql has the playsms table

When doing playsmsd sendsmsd Nothing appens! No messages! No errors! It stills there until crtl+c to abort

The browser is allways saying - DB Error connect failed

Please double check your configuration file path and service path, and database detail

otherwise give me the server detail, I will solve our issue.
