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

Nextcloud configuration:

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. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

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 config

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

Without access to your command line download the data/owncloud.db to your local

SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


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

As this seems to be a setup issue I would like to ask you to raise your question in the forums: https://help.nextcloud.com Keep also in mind that openwrt is not a supported platform. It should work, but we can't guarantee it.

See https://docs.nextcloud.com/server/14/admin_manual/installation/system_requirements.html for the supported platforms.

I looked at the source_installation. HTML page again.
https://docs.nextcloud.com/server/14/admin_manual/installation/source_installation.html
Prerequisites for manual installation; There is a problem.
Required:
PHP (>= 7.0, 7.1 or 7.2)
PHP module ctype
PHP module dom
PHP module GD
PHP module iconv
PHP module JSON
PHP module libxml (Linux package libxml2 must be >=2.7.0)
PHP module mbstring
PHP module openssl
PHP module posix
PHP module SimpleXML
PHP module XMLReader
PHP module XMLWriter
PHP module zip
PHP module zlib
In fact, a library is missing.
PHP module session.
After I added the library, it worked.
Please inform the website editors about this problem.
Installation and Inspection PHP（setup-nextcloud.php） did not find this problem.

@cooboyno111 Could I ask you to add it directly to this file here: https://github.com/nextcloud/documentation/blob/master/admin_manual/installation/source_installation.rst

There is a little pencil in the top right of the document which allows editing right here on GitHub.
