I found problem of facybox component.
It's cached config problem.
When I disable cached setting in administrator site, the facybox function affected.
Note: this problem also affect to themes.

Same problem brO :(

@Rose,

Try to replace fancybox/js/fancybox.init.php with

https://gist.github.com/lianglee/d8ec4e4ffad8b805d011

Syed Arsalan Hussain Shah BrO some image is open in fancybox so large, i want every image is open in fancybox limited size.

@ Nguyễn, strange, it should work when you click on image, make sure the fancybox is loaded in your page.

Make sure following url works:

https://cdnjs.cloudflare.com/ajax/libs/fancybox/2.1.5/jquery.fancybox.min.js

I installed success component & enabled it.
But it don't affect in news feed.
When I click image, but it don't show fancybox.

when click on image. then image will bhi disappear in news feed.
after refreshing the page image show back again.

Arsalan, I just posted a possible fix below the fancybox component

yeah its a great and thank you Arsalan shah brO, but one problem in it, when i click on image after view i click to x sign, then image is hide to the wall,
