This is an SSL error which means that some components of your website are not loading securely with HTTPS. According to Cloudflare, HTTPS is a secure way to send and receive web traffic in your browser. All HTTPS traffic is encrypted in order to increase data security. This becomes more important if a website is transmitting sensitive data like login and credit card information.
Fixing the issue in WordPress Finding the problematic resources and fixing the error
If you send data through normal HTTP protocol, it will not be encrypted and can be read using network packet analyzers like Wireshark. This error usually comes in both Google Chrome and Firefox. Both the browsers will show the error in their address bars and the SSL lock sign will not turn green. The green padlock in the address bar before the URL means the site is fully secure. Before moving forward, make sure that your SSL certificate is valid and properly installed. To check the SSL Certificate, you can go to SSLShopper SSL Checker page, enter your domain name and press the Check SSL button. It will automatically detect and diagnose if a valid SSL certificate is installed.

For this, there is a wonderful service called Why No Padlock. Just go to https://whynopadlock.com, enter your problematic URL and wait for it to process. It will list down all the resources which are loading with HTTP protocol instead of HTTPS.
