@ollblo – This could be caused by a few different things. A conflict with another plugin, a conflict with the current theme, or the Permalink structure you are using … have you checked to see if these are affecting you site causing you to see this issue?

I have deactivated all plugins exept Nextgen.
A have latest vwrsion of Twenty Twelve.
I have no conflict in permalink stucture.
Maybe I have to upgrade wp to 3.8???
@ollblo – It is always recommended to stay current with the latest stable WordPress release … although I do not expect it will resolve the issue you are seeing. Please submit a Bug Report (http://www.nextgen-gallery.com/report-bug/ … please reference this topic) with your site details so we can try to help you get this sorted out.
Thanks!
