In edit configuration of a course i try to load files, it seems fine but finally the file preview doesn't load.
The file is listed in attachments but the preview is not seen.
When i clicked in the item a dialog box appears with a form with file name, author, license and so on, besides the file information appears like file size and pixeles
I can copy the file path and download it to see in the my pc.
Also i configured the config.php fie to debug
@error_reporting(E_ALL | E_STRICT); // NOT FOR PRODUCTION SERVERS!But no error shows in page, also the permissions of moodledata are in 777.
@ini_set('display_errors', '1'); // NOT FOR PRODUCTION SERVERS!
$CFG->debug = (E_ALL | E_STRICT); // === DEBUG_DEVELOPER - NOT FOR PRODUCTION$
$CFG->debugdisplay = 1; // NOT FOR PRODUCTION SERVERS!
I added a screenshot.
How can i fix this?
