Icon links showing a stop sign when I try to click

My page has not been published yet officially because I am in the process of building it out. I have set up the links to the social media icons for the page. However, when I hover my mouse over the icons, the only one that is clickable is the Twitter one. My Instagram, Pinterest, and email link won’t let me click on it. I was wondering if there was something I needed to do to fix this?

Or would I officially need to publish my site before I can click on these links? If so, why can I click my Twitter icon?

Thanks!
