@computersimple, it has never been possible to upload the gallery from a single image. In the years, the easiest solution I’ve ever seen is this here, last post.

P.S.: Please, next time use an appropriate title for your topic.

@flyfisher842, have you changed URLs or domain name?

@sjtr, any other lightbox effects (shutter, fancybox, etc.) isn’t working at all? Try one of them, but you may also need to clear the browser cache.

Edit: check wp_header call too

@sjtr, you have to put <?php wp_footer(); ?> immediately before </body> tag. I can’t tell you where you have to put it (in which template file), I assume you know it since you did the theme.

@hmpk, open your own topic, you can’t have answer in someone else’s thread

@imrvirus, how many columns have you setted in the options?
You have an “Easy Columns” plugin activated, maybe it could interfere, have you tried to disable it?

@balota, check if you have a script or a plugin that disable the image saving with the right click. Deactivate all of your plugins (except Nextgen) and activate default theme and see if the actions over images comes available. In Firefox they should be, more or less, “view, copy, save image as, email, set as, view image info…”.
If not, try to change your Nextgen lightbox effect to something else, e.g. shutter or fancybox. Currently your Nextgen images, when opened in lightbox, are seen as links, that’s the reason why you can’t save them.
And then, even if this is not related to the issue, update Nextgen to the last version.

@chrishpz no, updating the plugin doesn’t remove galleries.
Maybe you could experience issues if you are using NG extension plugins no longer compatible, if you have created your own custom gallery templates or if you have heavily customized things, depends on what older version you’re talking about.
