Using WordPress 3.0, Thesis 1.8 and NGG Version: 1.5.5
Manage Gallery -> Gallery -> edit Thumbnail produces this error:
Fatal error: Cannot redeclare ngg_getonlyimages() (previously declared in ../nextgen-gallery/admin/functions.php:1456) in ../nextgen-gallery/admin/functions.php on line 1460
When I comment one instance of the function out then a similar "..Cannot redeclare..." error returns for another function in the same file.
Thanks for a great plugin and any support you could offer!
