UddeIM uses
Code:
echo "<a href='".uddeIMsefRelToAbs("index.php?option=com_kunena")."'>";
function uddeIMsefRelToAbs($value) {
// Replace all & with & as the router doesn't understand &
$url = str_replace('&', '&', $value);
if(substr(strtolower($url),0,9) != "index.php") return $url;
$uri = JUri::getInstance();
$prefix = $uri->toString(array('scheme', 'host', 'port'));
return $prefix.JRoute::_($url);
}
to create the link. So "index.php?option=com_kunena" is translated into the absolute link usign the Joomla framework.
When this fails there is always a problem with the Joomla configuration or the installation itself is broken (e.g. an error in the Joomla database).
