@spavli2 – It would be much better to provide a link to your site than to provide a link to a “paid” theme … and upgrading to NextGEN Plus or NextGEN Pro would not likely correct the issue of the Lightbox not working.

@spavli2 – Try changing your WordPress Permalinks from the “Default” to something else such as “Post name” or “Month name” … see if that helps to sort out this issue.
Thanks!

@spavli2 – Have you tried using the Reset Option under Gallery > Other Options; and then clear your image cache under Gallery > Other Options > Miscellaneous?
Something appears to be affecting the paths to the resources NextGEN Gallery uses and the above may correct it.

reset all to the default solved it.
Thanks!
