Hi megas

I'm sorry, not really sure what you mean: you installed Joomla3 3times, or jOpenSim3 3 times?

If jOpenSim3: did you uninstall it the other 2 times? If yes, you removed all database tables and of course will not see any old groups/profiles anymore.

The error number 3 is not jOpenSim related, but has got something to do with OpenSim. I've seen that messages quite a while ago with some user, but cant remember anymore what exactly the issue was. If I'm not completely wrong, it was something about manually compiling ... but not 100% sure.

Hi megas

I'm sorry, but I'm still a little confused about what u installed when and how.

The only way I can imagine, this error message can be caused by jOpenSim is when you lost only partial group data while reinstalling. jOpenSim stores data for groups in 7 (!) database tables and they should reference well together. If data of one table is lost, most others are pointing to "nowhere" then.

Specially the table #__opensim_groupactive is called during login, responsible to give the user the last active group again. If there is an invalid/broken reference, I can imagine such a message during login.

If your group data got lost when reinstalling, I think the best solution is to empty this table as well. Users with an existing and working group will not loose their membership, but might have to reactivate their current group manually when next time logging in.

Hi megas

You probably use a different database (or different db-prefix) for Joomla 3.x than for Joomla 2.5.x and did not move/copy the database tables of jOpenSim to there (see notes at wiki.jopensim.com/index.php/Migration_jOpenSim )
