I know this issue too. Try not to intend your section content and remove white-space at line endings.

@section('div-id')
test_id
@stop

@section('content')
@lang('texts.test')
@stop

Thank you for you quick answer, it works for the first white-space (not always though), but not for the second. I checked and I have no white-spaces or tabs at the end of my lines. If I remove the CR LF, it's not working at all (it appears there need to be a line break before the @stop command).

Result with your input is:

<div id="test_id ">
  <p> test </p>
</div>

I don't know why it doesn't fix the first white-space of the 'content' section tho.

Ow, that's great to know, thank you!
