Hello Krileon,
thanks for your help. But it's still not working...
I spent several days trying to understand what the problem is... I even reinstalled a clean joomla 3.9.11 platform and latest community builder (and latest CB Activity, CB Auto Actions, CB Conditional, Cb Footer Removal, Cb ProfileBook, Cb Query Field).
In CB Plugin Management I published the system autoaction "CB Articles - Create" (access everybody), I then created two users from the frontend CB registration page, I connected everyone with each other and I started to "make experiments". Everything is published, everything is working but...
If a user create a joomla article from frontend, it is NOT published in the activity wall of other users, even if it is showed in the "articles tab" of the user's profile (I tried with user as Publisher, Admin, Superuser)...
On the contrary, If a user creates a CB Blog, it is correctly published in the activity wall of other users...
At the end... It looks like the "CB Articles - Create" trigger is not working (at least in my case)..
I'm still wronging something somewhere?...
How can I solve this problem? Can you guide me again in the configuration of the CB Auto Actions plugin to make Joomla articles shows in the activity stream of users?.. I If you want I can give you the credentials to enter my website backend and check what's wrong...
Thanks again in advance for the help.
