Is not displayed Safari browser

Are you getting any JavaScript errors on the page?
(in Chrome you open the JavaScript console by pressing CTRL+SHIFT+J keys together – I’m not sure how to do that in Safari)

Also try ticking the “DOMContentLoaded event” checkbox under “Other Settings”.

What is the URL of the page in question?

The url is: https://np.unydev.ro/

I did what you said but it doesn’t work.
Thank you

Can you tell me whether the SA sliders on this page:
https://edgewebpages.com/
Work within your Safari browser?
