Creating user does not work

If I try to create a new user on the admin panel it does nothing. After refreshing the page it cannot load the correctly anymore just a white page. The request is getting rejected with a 500 server error.
After restarting the server I can use it again but still no chance to create a user.

In the Nextcloud log is nothing interesting.

The Nginx log show the following message:
2016/12/13 21:20:29 [error] 859#859: *610 FastCGI sent in stderr: “PHP message: PHP Fatal error: Couldn’t find implementation for method 03ƒmr::__tostring in Unknown on line 0” while reading response header from upstream, client: CLIENT, server: SERVER , request: “GET / HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.0-fpm.sock:”, host: “SERVER”

I am running Nextcloud 11.0 on an nginx server with PHP7 and an MySQL DB - Debian

Would really appreciate your help.
Kind regards

Cannot create a normal user. I can however create a new group but when i fill in a username and password and click create something stops working. no matter if its a excisting group or new group or no group everytime I have to restart apache2 to get it working again.

the admin user seems to work data and client
Am I allowed to add a user manually by command line sql?

Solved the above issue where you cannot create a new user.

The problem is with the password in the Admin additional settings at the bottom you can set the password strength

Password policy

Minimal length 8
x Forbid common passwords
x Enforce upper and lower case characters
x Enforce numeric characters
x Enforce special characters

if all is selected and you try and create a user with a weak password which not meet the requirement something breaks and every reload shows a blank page. reloading apache service solves the issue and using a password which do meet the requirements creates the user without any problem.

Seems to me I should be alerted that the password is not correct instead.
BUG?

Everthing is working perfectly now.

The same issue with freshly installed Nextcloud 12

Has this already been reported on github?

(same issue, same reproducability with fresh install on Debian, PHP7.0/Nginx)

I am reporting it now as I got the issue again.
I currently just use the occ to create users like:
sudo -u www-data php occ user:add --display-name=“Layla Smith”
–group=“users” --group=“db-admins” layla

After that it asks you for a password.

REFERENCE URL: https://github.com/nextcloud/server/issues/5746

An error occured during the request. Unable to proceed.
same error
creating user or group

can’t creat any at all
