Lightbox display not working in NTS Kay 5.2.3

Hi Hung

I have just bought some themes with new developer license, to help you out a little and to say thanks for all your help

I am happy to keep using older version of Kunena 5.0.14 and NTS Kay 5.1.2, until the last problem is fixed.
There is no rush...

On my Test Site, I have installed Kunena 5.1.1 and NTS Kay 5.2.3
Everything is working very well now, except for one thing.
The pop-up Lightbox for Image display has stopped working in NTS Kay 5.2.3
I have never had a problem with Lightbox before this.

Lightbox for image display is working 100% OK in Kunena 5.0.14 and NTS Kay 5.1.2

I have 2x links for you that show what I mean:

#1 Here is link from my Test Site that shows Lightbox not working (Kunena 5.1.1 and NTS Kay 5.2.3)
When you press any image, nothing happens.

#2 This second link is from my LIVE Site and shows Lightbox working OK (Kunena 5.0.14 and NTS Kay 5.1.2)

No one has replied to my message yet, so I asked the same question on the official Kunena.org Forum here:
www.kunena.org/forum/k5-1-support/153359...-kunena-5-1-1#202579

One the of the Kunena Developers has replied to my question about Lightbox not working, and has explained this:

We have updated the lightbox with a new version, now the lightbox has fixed many mobile issues ect.

If the kunena template has the old version, then it should work also. But only if they have all the html files. If they don't have all the html files, then it loading the crypsis html file. Then you will get old and new html code. This can be the issue on your kunena template.

Can you please comment on this Hung ?

Thank you,
regards Derek

I join @dexter33's opinion that the lightbox is not working. We expect a solution to this bug - All photos are displayed below the footer on the page.

Best Regards

Reason for the bug: Missing file fancybox.css in /components/com_kunena/template/nts_kay/assets/css
Solution: Copy all files whit name fancybox from /components/com_kunena/template/crypsisb3/assets/css to /components/com_kunena/template/nts_kay/assets/css

Thank you ciklon for posting this solution !!!
It works beautifully

Now I can finally upgrade Kunena on my live website.
