Photos of the album don't link to their gallery

I did the Markup Validation Service of the site and noticed there are errors.
How can I fix this errors.
There is a way to do it automatically with some software?

I.E.: I can see this invalid code….but why it refers to facebook? I cannot see anything about it…where is hidden this facebook?

Error Line 2, Column 180: Attribute xmlns:og not allowed here.

@stesenso – Without a link to the page/post where this is happening there is not much we can offer in suggestions or ideas for troubleshooting … would you be able to share one?

@stesenso – Thanks for the link … it looks like you are using an external Lightbox effect I would recommend ensuring the NextGEN Gallery option is set to no Lightbox under Gallery > Other Options > Lightbox Effects.

Also, it appears you are using the “minify” option for your W3 Total Cache installation, this may be causing issues as well.

You may also want to check for any other active plugin conflicts as well, just in case.

Thanks!

thanks
I have done all
I have also deactivated all the plugins, changed the theme, and back to the original theme and reactivated Nextgen gallery.
Now: why I have this problem (have a look, https://www.ikonox.com/gallery/)? Thanks

fixed now but it seems to be in trouble all the time

@stesenso – The Lightbox effect is still not being loaded correctly by your site as I am not seeing the appropriate code in the page source on your gallery pages.

This could still be a conflict with another plugin, or even still be a caching issue. It may even be your theme (but I do not think that is the case).

This may require a more in-depth look at your site. If you are still having issues please submit a Bug Report (https://www.nextgen-gallery.com/report-bug/ … please reference this topic) so we can get a closer look.

We will need log in and FTP credentials for your WordPress installation as well, please include those with your Bug Report.

Thanks!

hi Cais

before I did not activate Lightbox, it was no Lightbox: now, in Gallery-Other Options, I have Lightbox. Can you see the difference?

@stesenso – Thanks … everything is looking good.
