I have the same problem, it started a couple of days ago. I haven´t figured out wether it is caused by NGG itself or by other pic-related plugins.
I have deactivated and reactivated all plugins, deactivated other pic-related plugins, but no success.
The error message I receive from NGG is:
“An unexpected error occured. This is most likely due to a server misconfiguration. Check your PHP error log or ask your hosting provider for assistance.”
I have checked the Log file via myphp, that´s what it read:
08.04.2015 11:54:10 aconcagua.de [client 78.52.113.0] WordPress-Datenbank-Fehler Duplicate key name ‘path_image_size’ f\xc3\xbcr Abfrage ALTER TABLE wp_ewwwio_images ADD INDEX path_image_size (path(255), image_size) von do_action(‘admin_init’), call_user_func_array, ewww_image_optimizer_admin_init, ewww_image_optimizer_init, ewww_image_optimizer_install_table, dbDelta, referer: http://www.aconcagua.de/wp-admin/update-core.php?action=do-plugin-upgrade
I deactivated the mentioned Plugin EWWWIO (Image Optimizer), did not help.
Does anybody have an idea? Thanks for your help!
Kind regards

WP and NGG are both up to date.
I have also tried the advice from another thread to change to an Twenty standard theme, nothing changes….

@wishbonex – Yes, these forums do follow a different approach but its also one that recognizes the myriad differences that can and sometimes will cause things to not work correctly.
Thanks for starting your own topic.
