They are working on fixing this, in the mean time you can do this:
go to /wp-content/plugins/are-you-a-human/ and edit the “ayah.php” file.
Change this:
foreach($config as $key => $value){
if(array_key_exists($key, $params)){
$this->{$key} = $params[$key];
} else {
$this->{$key} = $value;
}
}
to
foreach($config as $key => $value){
if(array_key_exists($key, $params)){
$this->$key = $params[$key];
} else {
$this->$key = $value;
}
}
Removing the curly braces around $key in both instances fixed it for me.
Good luck!
