If, in the User Manager, a user is registered with the Real Name containing a comma, dokuwiki will throw an error when sending a notification.
If a user is regisered with the following real name:
van Beethoven, Ludwig
When enabling Notify user, and click on Save Changes, the error which appears on the top of the window is:
E-Mail address <Ludwig> is not valid
The line in conf/users.auth.php could be like:
lvb:$1$3OfqaqQs$.Qw0Djwq4eGG9ii.Vha3R/:van Beethoven, Ludwig:firstname.lastname@example.org
Probably the comma and colon are both interpreted as delimiter. Can someone confirm this?
