Problem to upload image files

I try to upload image files (jpg, gif…) for shop logo or products item.

The error is …It is not allowed to create/upload/rename files of the application/octet-stream MIME type.

Pls help !!!

Hello lagos,

Thank you for the message.

It seems that the problem occurred because of a minor bug in your store. In order to fix it, please replace the following part of the code:

if (!is_array($filtered[$id]) || !empty($filtered[$id]['path']) && in_array(mime_content_type($filtered[$id]['path']), Registry::get('config.forbidden_mime_types'))) {

with this one:

if (!empty($filtered) && (!is_array($filtered[$id]) || !empty($filtered[$id]['path']) && in_array(fn_get_mime_content_type($filtered[$id]['path']), Registry::get('config.forbidden_mime_types')))) {

replace the following part of code:

$mime = mime_content_type($filtered[$id]['path']);

with this one:

$mime = fn_get_mime_content_type($filtered[$id]['path']);

and replace the following part of code:


with this one:

function fn_get_mime_content_type($filename)
if (class_exists('finfo')) {
$finfo_handler = finfo_open(FILEINFO_MIME);
$type = @finfo_file($finfo_handler, $filename);
list($type) = explode(';', $type);
} elseif (function_exists('mime_content_type')) {
$type = mime_content_type($filename);
} else {
if (strpos(basename($filename), '.') !== false) {
$type = fn_get_file_type(basename($filename));
} else {
$type = 'text/plain';

return $type;


in the “fn.fs.php” file located in the “core” directory of your CS-Cart installation.

Thank you Anastasiya, for your replay.

I look to fn.fs.php file in core directory. I have the right code for the first and second and when i replace the third code to the end of file and save, i can't load the main page of my shop.

Maybe i must try differens else.

Thank again
