Dear vtrs,
Sorry for not replying to your post earlier. Apparently, we didn’t get notifications from WP about this. Although, I have checked that Vuukle is working with 3.5.1 – https://hotelmeridianplaza.com/?page_id=127
May be there is something else causing the issue, could you please share the site where you would like to test Vuukle so I can have it looked by our WP specialist.
Apologies for the inconvenience.
Cheers,
Ravi
