Did you specify the $table->rowsTemplate value? 🙂
It's required for a front DB Helpers if I'm not wrong.

You need to establish a connection to the external/remote database you want to use, and then run the queries with the usual framework code to retrieve/display the data:
 
The first codebox shows an example of how to start an external database connection.

By default on new installs, you would use email address to login. Did you use the email specified when you setup the software?

Try logging with a different browser, or clear the cookies and cache of the browser you are using.

One example I use:
/** * Send pm */ public function messageMembersSend( $member, $subject, $content ) { /* Setup pm title and msg */ $msgTitle = $subject; $msgPost = $content; \IPS\Member::loggedIn()->language()->parseOutputForDisplay( $msgTitle ); \IPS\Member::loggedIn()->language()->parseOutputForDisplay( $msgPost ); /* Set the receiver */ try { $member = \IPS\Member::load( $member ); } catch( \OutOfRangeException $ex ) { return; } /* Set pm sender */ try { $pmSender = \IPS\Member::loggedIn(); } catch( \OutOfRangeException $ex ) { return; } /* Valid sender? */ if( !$pmSender->member_id ) { return; } /* Create conversation */ $conversation = \IPS\core\Messenger\Conversation::createItem( $pmSender, $pmSender->ip_address, \IPS\DateTime::ts( time() ) ); $conversation->title = $msgTitle; $conversation->to_member_id = $member->member_id; $conversation->save(); /* Add message */ $message = \IPS\core\Messenger\Message::create( $conversation, $msgPost, TRUE, NULL, NULL, $pmSender ); $conversation->first_msg_id = $message->id; $conversation->save(); /* Authorize everyone */ $conversation->authorize( $member ); $conversation->authorize( $pmSender ); /* Send notification */ $notification = new \IPS\Notification( \IPS\Application::load('core'), 'private_message_added', $conversation, array( $conversation, $pmSender ) ); $notification->send(); }
