Hi Stella,

Step 1:

First go and edit “components/com_content/router.php“, then continue on step 2. Note: Remember, you have to repeat or re-do following steps everytime you update Joomla!. 

Step 2: 

(There are two places need to do this change, one near the top, one in the middle) Replace this:

$advanced = $params->get('sef_advanced_link', 0);

With this:

$advanced = $params->get('sef_advanced_link', 1);

Step 3: 

Replace this:

->where($db->quoteName(‘alias’) . ‘ = ‘ . $db->quote($db->quote($segment)));

With this:

->where($db->quoteName(‘alias’) . ‘ = ‘ . $db->quote($segment));

and now you're done.
