toFile() not working any more

Hello texnixe

Many thanks for this clarification. In this case I do not need panel support. Interestingly that toFile does not work on HTML-files. I managed to get it work, finally:

 $file = $page->content()->contentfile();
 $filename = $page->root()."/".$file;
 if ($filecontent = readfile ($filename)) {
    echo $filecontent; 
 }

Also refers to this earlier issue: Display content from HTML file on a page?
