Same here. Still on 1.9.13 and looking for an alternative. However, I got a first reply asking me for the exact SEO plugin. If you would like to follow the discussion – it’s here.
Thanks for the fast reply. I have the same settings checked. But I also have excluded ngg_tags from the sitemap. I therefore doubt that it is a problem related to the SEO plugin. Might as well be caused by the gallery itself…? I also posted the question to the gallery support forum – will see if they find something.
As far as I understood from the Google translater… same problem here. Did you find any solution or at least the reason for the soft 404’s?
