Answer 1

So the answer is in the question itself ... do a check on the text of the message and then display it. Or find out why there is no this variable...

Answer 2

Go to controller succes.php and languages ​​succes.php
And search there
In the language you should have a translation of this variable
$_['text_mesage'] = 'Your text here';
And in the controller, you must take it from the language and assign it to this variable.
Something like this
$this->data['text_message'] = $this->language->get('text_message');
Most likely, this variable is not declared and assigned in your controller, but you stubbed it in the file.
