I created galleries with nextgen and it works great! I added galleries to an album and show the album on a page using the shortcode: [album id=1 template=extend].
This all looks great, but when I click the gallery on the album overview page it redirects to the error page mentioning that the page is not found?!
Album page: http://itf-taekwondo.nl/?page_id=1098
Links redirect to error: http://itf-taekwondo.nl/?page_id=1098&album=1&gallery=115
I tried creating a page for every gallery and disable the "Deactivate gallery page link" option, but nothing gets it working.
