We have purchased jms multisites and have everything installed and patched. version 1.3.27

we have gone through the initial training with you and still cannot seem to get our slaves to add correctly

we use addon domains (unique urls not subdomains)
when attempting to add a slave site (using various different templates) we recieve the following error
Error
Jms2WinFactory::_createDBO_BasedOnConfig: Could not connect to database
DB Error number: 0 -
driver => mysqli
host => localhost
user => ppcnorth_mcbbcom
database => ppcnorth_mcbbcom
prefix => ads_


what should we look at to fix this issue?

edit:
here is an example of the domains and the structure.

ppc.domain.com : used as the master site and to publish RSFORM PRO content and articles available to slave domains
this gives us a portal to edit content for all assigned domains (currently ~30) and
use common rsform content for each

anklesite.com : will publish content from MASTER with category anklesite and RSFORM Content
kneesite.com : will publish content from MASTER with category kneesite and RSFORM Content
...many more domains

let me know how to best approach this this goal

The message that you report is displayed when JMS need to create a DB for the slave site and for which it does not has a MySQL user that has the permission to create the DB.

In general, under cPanel, it is easier to create the DB under cPanel before proving the information to JMS.
OR you should have to provide to JMS the MySQL "root" login to allows creating DB dynamically. Such "root" login and password can be setup inside the "Setttings" menu present in JMS.

If you share the "RSForm" extension, this mean that you will have the same RS Form content in each website.

You mention publish content from category.
I don't remember that RS Form has categories for the display of their content.

If you make reference to the Joomla / Content menu and categories then you make reference to the Joomla articles and their categories.
In this case, if you want to diplay the articles present in a specific category of article, this is possible with the "Article sharing for JMS" that allows displaying an the articles coming from another websites.
