Hi, I am using the lastest multisites version:
Joomla Multi Sites version: 1.2.87 (Latest available: 1.2.87)
Patches definition version: 1.2.81 (Latest available: 1.2.81)
I created a full site copy in a new db using multisites.
Joomla ver 1.5.26
I have gantry installed with a rockettheme template and for some reason the roknavmenu module does not work and throws the error below:

"Warning: require_once(/home/REMOVED/public_html/REMOVEDgantry-fusion/formatter.php) [function.require-once]: failed to open stream: No such file or directory in /home/REMOVED/public_html/REMOVED/modules/mod_roknavmenu/lib/renderers/RokNavMenu1XRenderer.php on line 220

Fatal error: require_once() [function.require]: Failed opening required '/home/REMOVED/public_html/REMOVEDgantry-fusion/formatter.php' (include_path='.:/usr/lib/php:/usr/local/lib/php:/home/REMOVED/php') in /home/REMOVED/public_html/REMOVED/modules/mod_roknavmenu/lib/renderers/RokNavMenu1XRenderer.php on line 220"


line 220 in RokNavMenu1XRenderer.php points to this:
public function getFormatterPath(&$params) {
global $mainframe;
$theme = $this->getThemePath($params);
jimport('joomla.filesystem.file');
// Get the formatters path
$formatter_path = JPath::clean(JPATH_ROOT . $params->get('theme', $theme) . "/formatter.php");

$template_default_formatter_path = JPath::clean(JPATH_ROOT . '/templates/' . $mainframe->getTemplate() . '/html/mod_roknavmenu/formatter.php');
if (JFile::exists($template_default_formatter_path)) {
$formatter_path = $template_default_formatter_path;
}

//see if the backwards compat custom_formatter is set.
$template_formatter = $params->get('custom_formatter', "default");
$template_named_formatter_path = JPath::clean(JPATH_ROOT . '/templates/' . $mainframe->getTemplate() . '/html/mod_roknavmenu/formatters/' . $template_formatter . '.php');
if (JFile::exists($template_named_formatter_path)) {
$formatter_path = $template_named_formatter_path;
}
return $formatter_path;
}

To me it seems that something is wrong with the symbolic links pointing to it in the master folder. I could be wrong. Any help is appreciated. Also notice that "Warning: require_once(/home/REMOVED/public_html/REMOVEDgantry-fusion/formatter.php)" doesn't have a forward slash in between my "REMOVED" directory and "gantry-fusion". Let me know if you need any more information

It is not easy to imagine what is the value of REMOVED.

The error message report that a file is missing.
Check the path to identify what is not correct in the path.

I suspect that the gantry library is NOT present and should be installed in a specific path that is NOT there.

Rocket themes have several implementation of gantry.

Sometimes, this is a component, but I think they also had a plugin that contain the gantry library.

In the code that you provided, it seems that it search in the /templates directory for a template that contain the module roknavmenu.

Perhaps that you don't have any "html/mod_roknavmenu" defined in the slave site template selected.

The "REMOVED" part tells you the name that we suspect if NOT present.
