After upgrading to 2.10 and subsequently to 2.11, we are not able to upload any files no matter if they are saving to DATABASE or DISK, throwing "

INTERNAL APPLICATION ERROR

Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.

We've tried with regular sizes some tenths of k.

# --- Attachments / File Uploads ---
$g_allow_file_upload = ON;
$g_file_upload_method = DATABASE;
$g_absolute_path_default_upload_folder = ''; # used with DISK, must contain trailing \ or /.
$g_max_file_size = 5000000; # in bytes
$g_preview_attachments_inline_max_size = 256 * 1024;
$g_allowed_files = ''; # extensions comma separated, e.g. 'php,html,java,exe,pl'
$g_disallowed_file = ''; # extensions comma separated

So it worked before? Which version did you use before the upgrade?

Sorry, I've misled you: we have a 2.10 fresh installation, subsequently upgraded to 2.11. It was installed with a 5.6.30 PHP version

Do you get any errors or warnings when running admin/check/index.php ?

Have you enabled PHP fileinfo extension?

I don't know doing this.
Please instruct me how to do.
Thank you

PHP fileinfo extension was not enabled. I enabled it and solved the problem.
Thank you!

@radub, can you please specify the steps to enable the PHP fileinfo extension? Thanks!

Stumbled against the same problem with IIS and the solution was to add in
c:\program files\php\v7.2\php.ini

This line:
extension=php_fileinfo.dll

along with the other items in: [ExtensionList]

Thanks LucVd
Adding extension=php_fileinfo.dll in php.ini file worked for me in IIS server
