Hi,
this is a template problem, in file templates/theme3050/includes/includes.php after line 45 you have:
$hideByView = false;
switch($view){
case 'article':
case 'login':
case 'search':
case 'profile':
case 'registration':
case 'reset':
case 'remind':
case 'form':
$hideByView = true;
break;
}
//By Component
$hideByOption = false;
switch($option){
case 'com_users':
case 'com_search':
$hideByOption = true;
break;
}
//By Component
$hideByEdit = false;
if($option == 'com_content' && $layout == 'edit'){
$hideByEdit = true;
}
Your template disable all modules in article,login,registration,edit profile,search.... pages. I don't know why,
this is not a feature, this is a un-feature
Joomla have many options to manage modules and pages. So, this code is very unless, it remove Joomla features.
