After installing the second slave site I received this:

Extensions - plugin manager - User partial user sharing

Basic Options:
Sites selection: Selected only
sites: Fatal error: Call to a member function setQuery() on a non-object in /home/soft/public_html/registrace.mimino.cz/administrator/components/com_multisites/classes/multisitesdb.php on line 479

Any hints?
Thanks, Zdenka

As you didn't provided any version number of JMS and partial user sharing, it is difficult to retreive this line.

What I suspect is that you try to access and DB that does not exists anymore or for which you have changed the password (and thereofre on which you don't have anymore access).

The DB connection has failed and therefore subsequent queries may crash.

Hi,

thanks for the answer.
Actually problem was solved with writing:

$db=JFactory::getDBO();

before command on line 479 - that was:

$db->setQuery( $query );

You still didn't provided the JMS version.
So we can not cross-check the code for sure.
We did the hypothesis that you are using the JMS 1.3.24 full.

I can just tell you that it is not recommended to always using yhr JFactory::getDBO() because this will access the current DB (probably the master) and NOT the slave site DB.
So the result will be unpredictable.

To fix the issue, it would be better to identify the slave site that has a wrong DB connection information.
