The plugin is looking to see if you have the template in your theme nggallery folder first before it accesses the template in the plugin view folder. That seems to be where the incompatibility is and by creating the folder in your theme directory and placing the template there it works.
The way to get Nextgen-Galleryview to work is to create a folder called nggallery in your theme folder (you can use the
for Pagelines) and copy the gallery-galleryview.php template from the view folder of the plugin and put it in the nggallery folder.
This is from the plugins readme file that talks about Advanced Configuration:
- Create a folder called "nggallery" within your Wordpress theme.
- Copy "gallery-galleryview.php" from the "view" folder of the plugin and place it within the nggallery folder you created.
- When adding a gallery via the shortcode add template="galleryview"
