Dear all,
i'm using the following antispam in multilanguage mode:

but, randomically, in the frontend I have:

where "Array" label appears, instead of the right message like:

It seems a problem related to the multilanguage, because in another site I'm developing without multilanguage, it doesn't occurs and message is correctly written.
I'm using PHP7.0 and Joomla 3.9.2 with latest Chronoform version
Do you have any suggestion?
Regards
