User clicks the link 'Report this user' below a message, fills in the form and submits it.

Result:
Comes back to the same form. The following error message is shown 'Error

wrong database cell ?

have you entered a mail on the kunena configuration, else there is a bug with joomla mailer.

Yes, email is properly set. It worked perfectly in the past.

try change this:

github.com/Kunena/Kunena-Forum/blob/deve...lers/topic.php#L1611

to:

There is a bug on joomla, should be fixed on next joomla version, until then use this fix.

[strike]thanx, trying....[/strike]

The same Problem again, Invalid address: (username)

then you need to wait for Joomla 3.5.2
