2.2.5 Upgrade Problem: Embedding 'Active Language'

I have one problem since upgrading to 2.2.5. I use the multiroot to point alternative domains to different languages versions.

However, in 2.2.5 the command 'activeLanguage' attribite seems to be being ignored in the multiroot alternative index.php:

$ret = GalleryEmbed::init(
array('embedUri' => 'http://www.alternativeurl.com/',
'g2Uri' => 'http://www.baseurl.com/',
'activeLanguage' => 'es',
'apiVersion' => array(1, 2)
));

Check browser preference is NOT selected

I have another site using an older G2 version on the same server, using this same technique with no problems...

Any ideas this?
