How to COMPLETELY DISABLE Smart Slider’s cache?

How can I configure Smart Slider 3 to never, ever cache anything?

I have a wordpress site that has an extremely efficient varnish cache sitting in-front of the web server, so very few calls ever actually make it to the backend. This wordpress site is actually served on two distinct domains: a normal clearnet domain, and a mirror of the site served on a .onion site.

The .onion site is essentially the exact same as the clearnet domain, except that I have a function with some hooks that convert links on the site from the clearnet domain to the .onion domain. This prevents users on the .onion site from clicking a link that ends-up taking them back to the clearnet site.

This works fine for all my plugins, except Smart Slider 3, which occasionally (somehow) caches the photos from the .onion site such that subsequent visitors to the clearnet site have broken image links because they cannot view the .onion site.

Where is the configuration button to just tell Smart Slider to stop caching everything?

Yes, I’m aware of the consequences of removing caching. Even if I don’t leave it permanently disabled, it’s important to provide an option to *entirely* disable caching (not just provide a button to clear the cache) for debugging purposes.
