My host has decided to take the move to php 5.3. It causes a "little" problem with the websites powered by Joomla 1.0: content disappears everywhere! Here is a simple solution to fix it:

Open /includes/Cache/Lite/Function.php and replace at line 74:

$arguments = func_get_args();

with:

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