Slideshow stopped working

Hi can you share your URL. Do you have a cache plugin installed?

Dear mbrsolution thank you for your answer.
My urls are https://www.athensdaycamp.gr/ and https://www.apsampelokipoi.gr/.
It seems that SlidingTabs is the problem but only at the first website. I use the same at the second website but when I deactivate it the problem is still exist. When I deactivate that plugin everything works well only at https://www.apsampelokipoi.gr/ but…I don’t have tabs..
I had this plugin in my websites a lot of time ago. Do you think that is a matter of compatibility with the new version of Slideshow?

And YES, now is working well.
Thanks a lot!
