CiviCRM Community Forums (archive)

Hi!
I'm using CiviCRM 4.2.7 on Joomla 2.5.9 and I'm having this troube:
When I enter my contact I can see Summary, Contributions, ... , I see also Activities with the number of activities related to me. If I click on it, I see the list and everything is fine.
If I take an activity from the list or I take a new one (supposing it is a "phone call") and I assign it to another contact, the list of the activities disappear from my contact file, and it prompts "Processing...". When I set the filter, and I choose just a specific type of activity, I can see the list of those activities that are not being assigned to other contacts. In this case, if I select "phone calls" from the filter list, I don't see anything, but if I select "meetings" I see all the "meeting" activities correctly. If I go to the table "civicrm_activity_assignment" and I clean the row, than I see everything again but, of course, the activity is not assigned anymore.
Can anyone help me solving this issue, please?
Thanks a lot!

Thank you Lobo!
I tried now on joomla.demo.civicrm.org from the admin panel. I created two new accounts, but if I go on the "demo" account either on the other two I created, I see the number of the activities next to the link on the contact file, but when I click on it, there's nothing on the list. Actually, seems to be the same problem I have, though in the demo version I can't view the full list of activities as I can do as super admin on my site.
There's any info I can give you to go deeper?
Thanks!
