Hi Edwin,

i have installed SSI for Domain on my websites
i.e on main site and sub domain like www.mainsite.com and www.forum.mainsite.com
but it is not working.

thanks

Did you read the documentation and verify the different step when it is not working.

Do you have installed and enabled the plugin in each websites ?
Did you checked that each domain and subdomain share the same MySQL tables for the users and sessions ?
Did you check that you use the same "secret" value in the configuration.php file ?

I make all this actions, but it did not work and There is no open session between the same sites as there is in the code page acceul master site:

<script src="test.master.be/plugins/system/multisites...ins/logout.php" type="text/javascript"></script>
and

ssi_domain_logout = true;

I do not know what's the problem??

Frankline

Check the script that is called and its return when you login on the website.
When you are logged, you should have a call with the login and have a return = true.

I suppose that you have a return false.

If you have a return false, verify your settings, also verify the secret value between the websites.

Do you use JMS with SSI Domain ?
Which Joomla version do you use ?

I suggest that you also review the SSI domain video that how to cross-check you configuration.
