developers of next gen gallery have sent a patch/replacement file that should correct this issue.
to replace the file here: ../wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/attach_to_post/module.attach_to_post.php
with this fix should have fixed the problem and apply the fix in the next patch plugin
[ngg_images gallery_ids=”1″ display_type=”photocrati-nextgen_basic_thumbnails”] works, why doesn’t “Attach Nextgen Gallery to post” work for page edited with gallery?
Thanks!
