Invalid Email Address - Unable to create user

At /index.php/settings/users or on /index.php/settings/user I am unable to add an email address.

On the user profile page, no error - it just won’t update.
On the add user page, Invalid Email Address error occurs, regardless of the email used - all are valid and either on the same domain as hosting or gmail or other.
Tried multiple browsers. Disabled ad-blocking.

It’s on shared hosting:

Apache Version 2.2.31
PHP Version 5.6.30
MySQL Version 5.5.51-38.2
Operating System linux
Path to Sendmail /usr/sbin/sendmail
Path to Perl /usr/bin/perl
Perl Version 5.10.1
Kernel Version 3.10.0-693.11.6.1.ELK.el6.x86_64

PHP version is actually 7.0

No ideas? :frowning:

Same bug here.
Could we activate debug log to investigate the problem?

Same bug here. Running NC 13.01

Problem was addressed before.
I assume this could solve your problem …

Resolution

Same problem here

When I update to the new version

How canI fix this?
