Slider work only when admin is login

I’ve never heard of, or had that problem reported before with Slide Anything
(and as far as issues go that’s a big one and I’d have received a ton of support threads/emails if this was in fact an issue with SA 😉 ).

I can only guess possibly:
1) maybe you have a content restriction (membership) plugin that restricts blocks on your page depending on user level, or
2) possibly you have another slider plugin running on this page that also uses Owl Carousel, that is clashing with SA. If this is the case, then try deactivating this other plugin – this will test whether there is in fact a clash.

Well there is an easy way to test whether ‘Advanced Custom Fields’ is causing the clash. Disable the plugin and then test. (you can re-enable ‘Advanced Custom Fields’ after this test).

If this does not solve the issue, then try activating another theme to see if there is a clash with the theme (you can always switch back to the Skeleton theme), and try deactivation other plugins. There will be a specific plugin or theme that causing this issue/clash – Slide Anything is running fine on 1000s of sites, so this is a result of a clash with some specific plugin/theme – and I would appreciate it if you identify the ‘culprit’.
