The Kunena team has announce the arrival of Kunena 6.3.6 [K 6.3.6] in stable which is now available for download as a native Joomla extension for J! 4.4.x/5.0.x/5.1.x. This version addresses most of the issues that were discovered in K 6.2 / K 6.3 and issues discovered during the last development stages of K 6.3 Note: Please go to the Kunena Dashboard after an upgrade so that the Kunena database tables are also updated.
The Function "Add subscriptions to categories" ( in "Users") does not work any more with new users.
It quits showing the green Message ".....has been added" but nothing is added. (Kunena 5.1.15)
When I try this function with an elder User (who already is or was subscribed to a Forum) it works. I can "delete subscriptions " and I can "add subscriptions".
The reason was that my new users where "too new". They had not visited the Forum until now. (I could reproduce it about half an hour ago by building a new test-user. ) The function worked after he had visited the forum the first time. That makes sense, by the way.
So it's no bug it's a feature.
Thank you for the immediate response !
