Now, let’s take a look at the different reasons why there’s an issue with your certificate. If there’s any issue with your certificate, the browser assumes that the data will not be encrypted properly and therefore it’s unsafe for the visitor to proceed and potentially hack your WordPress site. You – the website owner – will then see the warning “Your Connection is Not Private” which prevents you from reaching the site. If the browser is unable to validate the certificate or finds that it isn’t valid, it will flag the site. It will ensure the site is up to current privacy and security standards. If the website is using an SSL certificate, the browser will validate the certificate against the certificate authority. When you visit such a website, your browser (Google Chrome browser in this case) sends a request to the website’s server. To understand how errors can pop up with your SSL certificate, you need to understand what happens when you visit a website that has SSL installed. SSL prevents hackers from stealing this data and misusing it. This data could contain usernames and passwords, credit card information and private data of visitors and the website. When data is transferred to and from your website, SSL ensures this data is encrypted. What is an SSL certificate? SSL stands for Secure Socket Layer that adds a layer of security to your WordPress site.
