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/... no

Are you using encryption: yes/no no (not sure)

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/... no

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

same as previous commands

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.

Please provide nextcloud.log as the template requests.

The only information given is:

An unhandled exception has been thrown:
OCP\HintException: [0]: Memcache OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

Which makes me think the issue is not with this application.

[ulllupollllo]

im pretty sure that error was already there when it was working, everithing else is working just fine

[tcitworld]

Again, please post the details of the error displayed and the contents of your nextcloud.log file when doing the action. Otherwise I can't be of much help.

[ulllupollllo]

as i previously said there are no errors, the log is empty
my fault for not knowing how to properly use the template

You mentionned

big red error on the register page

What's the error text in question?

About the logfile not containing anything, you may try to lower the loglevel (to DEBUG) to see if anything else comes up: https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/logging_configuration.html
