I have 2 sites with joomla 1.0.15 and my hosting server update php from 5.2 to 5.3.2 last night, so i have no content pages (error : Parameter 2 to frontpage() expected to be a reference, value given in /var/www/html/includes/Cache/Lite/Function.php), so looking for a solution (until 1.6 will be ready) i found this patch :

Replace:

$arguments = func_get_args();

with

$arguments = func_get_args();
$numargs = func_num_args();
for($i=1; $i < $numargs; $i++){
$arguments[$i] = &$arguments[$i];
}

in includes/Cache/Lite/Function.php}
