Hi,
after many hours of debugging I've discovered a strange problem in my local joomSEF installation (on Windows system). There were many links to redirect to 404 page. In my remote server (linux) there were not problems...
It was depends by not correct $base variable that in windows system was a backlash and not slash.
I've modified code in sef.php at line 85:
if ($base == '//') $base = '/';
in this way:
if ($base == '//' || $base == '\/') $base = '/';
and the problem goes away.
Is right?
I hope this helps someone.
Cheers
