Photos open in a different way

[Mauro]

Hi everybody,
in my website https://www.sloveniabenessere.it in some areas like that here below
https://www.sloveniabenessere.it/en/Slovenia_Hotel/Slovenia/Hotel_Eco_Resort_Beneath_Velika_Planina_Kamnik/Prenotazioni_Vacanze_Slovenia_Terme_Hotel_Eco_Resort_Beneath_Velika_Planina_Kamnik/166
Photo Albums don’t use javascript that is present in original not cached website and open phot ina a different way
( here a result of opening oe enlarge a photo https://www.sloveniabenessere.it/images2011/450x301_ss/slovenia-kamnik-eco-resort-velika-03.jpg )
Does it depend from cache ?
How I could fix and have original result?
Thanks

Could you try (temporarily) disabling rocket loader? The script might be incompatible.

[Mauro]

Thank you.
I tried but nothing changed.
Should I purge cache ?
Thanks

Issue persists even after cache purging
