Hello,

Go to Manage SEF URLs and please post some examples of the URLs that do not work, both their SEF and Real versions.

Under Mangage SEF url, in the Real url column i have :
index.php?option=com_content&id=16&lang=fr&layout=blog&view=category&Itemid=29

then on the sef url i have
fr/combloux-la-perle-du-mont-blanc/blog


If i take the domaine + the SEF REAL URL, it makes
domaine.com/index.php?option=com_content&id=16&lang=fr&layout=blog&view=category&Itemid=29
when i type it in explorer, it gives the 404 error

the url that should be shown inside the SELF REAL URL should be :
domaine.com/index.php?option=com_content&view=category&layout=blog&id=16&Itemid=29&lang=fr

but when i correct the real url inside SEF, it still don't work.

The URLs look OK - the different ordering of variables does not matter for Joomla, JoomSEF just stores the URL with option variable first and then the rest in alphabetical order to search it correctly in the database.
What kind of 404 error does the URL produce? The browser 404 page, or JoomSEF 404 page, or Joomla 404 error page? Could you post your website URL or send it to my e-mail ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it ) so I can see the problem myself?
Thank you.
