Hi Edwin,
If I define my template for new slaves to Special Copy the templates folder and symbolic links are allowed can I make different changes in the template configurations backend (params.ini) for each slave site or dose that automatically modify the params.ini file for all my sites using that template?
Or do I have to copy all the templates folder in order to do that? The same principle should apply to the logo right?
Am I clear? thanks.

This is not because that you do a "special copy" that this change the way the "params_XXX.ini" is created and read.

"Special Copy" just define the way that the "/templates" directory is created.
See tutorial video 0.b slide 34

"Special Copy" = full sharing of the "/templates" directory
"Copy" = copy of the "/templates" directory.

When "template folder" = {deploy_dir}/templates this allow to install (and uninstall) template in the slave site.

Hi,
Let me say that your answer is quite aggresive, confusing and a little out of place. It dose not answer but dose confuse and takes me nowhere. Very sad of a payed service.

I would recommend you reading any cheap costumer service book.

Meanwhile thankyou for your time and have a nice day.

See tutorial video 0.b slide 34 that present the value that I provided to you in my reply.

You also have post in this forum that discuss this point.

Hi, I have the same problem.
The slave sites save params_MULTISITE_ID.ini but they read params.ini.
I followed Edwin's recomendation of debuging the /libraries/joomla/document/html/html.php to check if the correct params.ini is been called and I found it is not.
On the line 232 you have:

if ( defined( 'MULTISITES_ID')) {

but defined( 'MULTISITES_ID') returns either false or null so it procedes to the Else.
Now I just need to know why is the constant MULTISITES_ID is not defined. Does anyone have a clue?

If the "MULTISITE_ID is not defined, this mean that you are on a master website.
So, this is normal that you don't have a params_MULTISITE_ID.ini

The description that you gives seems to suppose that you are using a template company that use their own framework and that bypass the Joomla framework.
This is the case for RocketThemes Gantry framework, YooThemes WARP framework, Joomlart T3 framework and other framework.

In JMS Multisites, we provided a partial patch for gantry and T3.
We also provide a product that all provide additional patches for a set of template using WARP of Yoothemes.

So check if you are using a foreign framework that bypass the joomla framework.
