Okay, I did the switch using:
$editorname=isset($in['editor']) ? $in['editor'] : qa_opt('editor_for_as');
// Basic editor for mobiles
if( qa_is_mobile_probably() ) {
$editorname = 'Basic Editor';
}
Tested it and ... still the same problem! Linebreaks get removed. Now I have no idea where the problem is! Why is it working here in q2a but not in
http://www.klaustukai.lt/ ... I am loading another theme for mobiles. But how could the theme influence the line breaks? It's a riddle...
