After upgrade Nextgen Gallery, my custom fields appears in galleries, not in each image. I think it is a problem with database, because i remember when i installed Custom Fields plugins i had to run the URL
http://www.example.com/wp-admin/admin.php?page=nextgen-gallery-custom-fields/ngg-custom-fields.php&mode=upgrade where "example.com" is my site.
If I run it I see:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Someone has a solution for this?
