Hi,
I’ve encountered the same problem again.
Startupwp ver 2.5.2, with the nivo slider you provide with this package ( nivo slider 2.4.3 ).
I even tried to upgrade nivo slider but the code you provide in the package seems to be invalid ( as notified in https://startupwp.com/topic/activation-key-for-nivo-slider/ ).
What I need to do ? Do I need to install nivo ver 2.2 in any future installation of startupwp ?
Regards
