Thanks Kriesi.at team. All problems had been solved with your team support.
I have upgraded to V4.1 and slideshow is working now. The current issue is that I cannot find slideshow editor on back-end admin side.
Thanks for your help.
Thanks for quick response and useful support. After disabled all plugins and reactive, the hacked code stops running.
The current problem is that the home page slideshow stop working. Anyway to fix it please? I cannot see slideshow on admin side too.
Thank you and Best regards,
