Same problem here… After upgrading my WP to the latest version, I upgraded my NGG plugin and now I’m having:
Fatal error: Call to undefined function ngg_upgrade() in …/wp-content/plugins/nextgen-gallery/admin/upgrade.php on line 179
error.
My galleries are still showing up in front-end but in admin section I can’t do anything with NGG Gallery panel…. It keeps saying:
The script detect that you upgrade from a older version. Your database tables for NextGEN Gallery is out-of-date, and must be upgraded before you can continue. If you would like to downgrade later, please make first a complete backup of your database and the images.
The upgrade process may take a while, so please be patient.
Start upgrade now…
