A strange situation is happening.
All the aliases associated to SEFUrls where index.php is present have stopped working since a couple of days ago.
This is my situation:
MAIN URL:
www.siciliandreams.com
TEST URLS
REAL URL: index.php?option=com_content&catid=40&id=71&lang=it&view=article&Itemid=72
SEF URL (working): it/posti-da-vedere-in-sicilia/segesta
ALIAS (working): it/posti-da-vedere-in-sicilia/71-segesta
ALIAS (not working): index.php/it/posti-da-vedere-in-sicilia/71-segesta
ALIAS (not working): index.php/it/places-of-interest-in-sicily/71-segesta
ALIAS (not working): index.php/posti-da-vedere-in-sicilia/71-segesta
The "not working" alias return the 404 page that is customizable via JoomSEF (404 Log tab)
