I have the same issue, and it happens only when I enable or use the plus version of the plugin.
at this point I fully Uninstalled all the NGG and deleted databases for them, and reinstalled the NGG and NGG plus.
i have a Photo(album) and within it I place 2012, 2013, …2016 (albums) into them i place galleries.
I placed shortcode to Photos page for Photos (album), i can see the yearly albums, but when I open the albums, I do not see galleries in them, i disables Jetapack, that does not help.
Let me know, i had this issue in a long ago, and for this reason did not switch to Plus version. However today i got some time on my hands and decided to try to switch to it. and fail after fail, it just does not want to work for me at all. ??
Will be waiting for your answers,
Thank you, and I highly appreciate your attention and care!
