App Store not loading

[poisony]

Steps to reproduce

1. Fresh install of Nextcloud 11.0.2
2. Change datadirectory to another
3. Open Apps-page.

Actual behaviour

All apps are loading but it does not get connected to the App Store. Only "Enabled" and "Not Enabled" apps showing up.

Does this have to do with me changing the data-directory? How do I get this to work again?

Server configuration

Operating system:
Hyper-V NextCloud installation from techandme.com
Web server:

Database:

PHP version:

Nextcloud version: (see Nextcloud admin page)
11.0.2
Updated from an older Nextcloud/ownCloud or fresh install:

Where did you install Nextcloud from:
Techandme.com
Signing status:

Signing status

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

List of activated apps:

App list

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

The content of config/config.php:

Config report

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

or 

Insert your config.php content here
(Without the database password, passwordsalt and secret)

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

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

LDAP config

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

Client configuration

Browser:
All
Operating system:
Windows Server 2012 Hyper-V NextCloud Installation from techandme.com

I think I found the problem. I will test copy ALL content from the old datadirectory.

I solved it. Sorry for posting before trying more :)
