Sieve vacation plugin is broken, roundcube doesn't send autoreply

Help with Setup/Upgrade
1

Hi everyone,

I was trying to make some auto replies with roundcube vacation plugin, but no email was send at all.
Digging around in the logs I saw this:
/var/log/roundcubemail/vacation-sieve

<1tbfckap> Cannot load the script from ‘vacation’

And this
/var/log/roundcubemail/errors

PHP Warning: array_merge(): Argument #1 is not an array in /usr/share/php/Net/Sieve.php on line 303
Warning: Call to deprecated function rcmail_overwrite_action(); See bc.inc for replacement
Call to deprecated function Q(); See bc.inc for replacement
Call to deprecated function get_input_value(); See bc.inc for replacement

How do I fix this?

Thanks :}

PS

This is the sieve file
