Hello,
Your site does not work fine, every time we try to check the cache plugin settings we get http://prntscr.com/tz17ph
We did not find any code that could cause the issue with the cache bug. Besides, your hosting company told you that
The site headers return x-varnish: HIT which means the cache itself is actually working just fine.
So, cache works even if you can’t run debug.
Regards
