How to understand why the slider on bootstrap 3 fell apart?

Question

HTML

Hello. I can’t understand why the slider on the bootstrap https://dverishop-spb.ru/ fell apart in the morning, in the evening I see the picture as it is now on the main one. There is silence in the console, not a word about errors. Traditionally, no one climbed anywhere, did not touch anything. knows nothing. :)
and the second question, Google did not help unfortunately, this class js is why is it here and does this mean that my content is loaded with scripts? I didn’t make the site, but I have a problem that the search engine doesn’t see my texts, they said to check that the pages were html and not through js and letters were loaded by Ajax, and I don’t know how to check, but I see js which is not on a couple of dozen other reviewed sites saw.
