Warning: Parameter 3 to showItem() expected to be a reference
Modify the following things in the /includes/Cache/Lite/Function.php:
1.
from: $result = call_user_func_array(array($class, $method), $arguments);
to:$result = call_user_func_array(array($class, $method), &$arguments);
2.
from: $result = call_user_func_array(array($$object_123456789, $method), $arguments);
to: $result = call_user_func_array(array($$object_123456789, $method), &$arguments);
3.
from: $result = call_user_func_array($target, $arguments);
to: $result = call_user_func_array($target, &$arguments);
The difference is not that big, it's just a matter of adding a ampersand before the arguments parameter, &$arguments, in all cases for php to realize that things are being passed by reference.
