I updated to 3.8.9 but I have some troubles.
The plugin does not work but show this message
La password per la decodifica della cifratura non è impostata
that is original
The password of decoding is not set
I want to get rid of this but I dont know WHY this happens.
I see there is a problem with global $str_key; that contains the "password of decoding" but why?
