Hello,
When I installed Nextgen I'm getting the following error on the manage albums and manage galleries pages:
[Duplicate column name 'updated_at'] ALTER TABLE
wp_ngg_picturesADD COLUMN
updated_atBIGINT
When I manually tried to remove the column, it will readds the column and gives me the same error again. When I uploaded the pictures in a gallery that column isn't updated with values (NULL).
