Hi,
Your case is strange. It seem you have re-config module SNS Slideshow and static block for SNS Slideshow. I’ve checked and find our some issues:
– Static block is not right code.
– You have enable cache and module cache
==> Please disable module cache when you development your site
If after disable module cache then your site still error please re-install our quickstart, dont forget refer youtube video in our document
Thanks!
