Hi,

I'm trying to upload Excel spread sheets and Word documents to a sub-folder of /assets/.

As you can see by the screenshot I'm unable to upload them however I can upload other file types such as .jpg. This is despite the fact that they are listed as allowed extensions.

I have tried adding the following to mysite/_config.php:

File::$allowed_extensions[] = 'xls';
File::$allowed_extensions[] = 'xlsx';
File::$allowed_extensions[] = 'doc';
File::$allowed_extensions[] = 'docx';

and have tried adding the following to mysite/_config/config.yml as recommended here :

  File: 
      allowed_extensions: 
        - xls
        - xlsx
        - doc
        - docx

Any help would be appreciated.

Framework: 3.1.12
CMS: 3.1.12

Thanks.

Fix: Turned out to be an issue with XAMPP. Re-installed it and this worked fine. Not sure exactly what the issue was.

Ensure you're flushing after altering the config, or the changes won't take effect.
Ensure that your webserver has permission to read such files (should do by default, but worth checking).
