Double effect in a gallery post

WordPress does not have a default lightbox effect. If you’re seeing multiple lightboxes, you may have another lightbox plugin activated.

If you can provide some additional information, I’d be glad to take a closer look. Please see the instructions on reporting issues for details on the necessary information.

Thanks.

Wow ok sorry, It should come from my theme so. I’ll investigate this. Thanks

Thanks for the update. Please let me know how it goes.

Yes it is confirmed. Was coming from fancybox (theme) & lightbox plugin.

Glad to hear your issue was resolved.
