I have tried various changes to the configuration of both Kunena and UddeIM, clearing browser cache and using different browsers and various operating systems to see if there is any place where it does work. Result is that the message link still does not go to UddeIM but to the User profile.
The .htaccess file settings are as bleow
Should there be anything added or revoked or enabled?
This was a clean install of Joomla 3, CB 2, Kunena 4 and UddeIM (inc UddeIM Professional plugins)
Cheers,
Alain
