Google Chrome mobile is working fine, but definitely in error on Safari.

Is this the Safari browser on iOS or MacOS (or both)?

Can you clarify what you mean by “not showing”? Is this on the front page of your site (and, if so, can you provide a link so that we can see it)? My guess is that you mean that when you’re in WP Admin and try to list all posts, this isn’t working – if so, are you getting a blank screen or an error?

Thanks.
