  4. open the folder in windows explorer
  5. double click the excel file to view the content using microsoft excel
  6. microsoft excel app open but did not show anything

Expected behaviour

Actual behaviour

File content not show in microsoft excel (blanks)

Server configuration

Operating system: Debian 9.12

Web server: Apache

Database: MariaDB 10.1.44

PHP version: 7.0.33-0+deb9u7

ownCloud version:

Updated from an older ownCloud or fresh install: fresh install

**The content of config/config.php:**

Log in to the web-UI with an administrator account and click on
‘admin’ -> ‘Generate Config Report’ -> ‘Download ownCloud config report’
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

ATTENTION: Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove all host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

**List of activated apps:**

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

**Are you using external storage, if yes which one:** local/smb/sftp/...

**Are you using encryption:** no 

**Are you using an external user-backend, if yes which one:** no

#### LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM oc_appconfig WHERE appid = ‘user_ldap’;

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

i think this ASAP needs an update to the more recent version ownCloud 10.4.0. Maybe this issue is already fixed there?
