Hi @sheilahurtado!
The problem on your website is caused by some sort of cache, a caching plugin or server cache. The way you can know this is, that if you write a random parameter in the end of your url:
https://delifrut.com.mx/?1234
then the first time this page gets visited, you are seeing the not-cached version of it (when your slider is fine), while if you check the page again, you will see its cached version (where the slider is not fine anymore).
So you should turn off your cache plugins one after the other, to figure out which one causes the problem. If you figured it out, you could turn that plugin back on, just start to turn off its options one-by-one, and leave the option turned off, which creates the issue.
But if you turned off all your cache plugins, and it didn’t helped, you should get in touch with your server host and ask them about their caching, because if this is not caused by a cache plugin, then it can only be caused by server cache.
