So if your SiteGround website keeps showing the “Not Secure” warning, it’s probably not their mistake. Here are some reasons for this website killer and how to treat it. 

Why is your SiteGround site not secure? 

The “Not Secure” error warns visitors that they are accessing a website without a secure HTTPS protocol. In most cases, it points to a problem with an SSL certificate, but it can also be a server issue or a local problem with the browser, system settings, or your firewall.

No SSL certificate 

If you need a short reminder, SSL (Secure Socket Layer) is a web protocol that encrypts the connection between the browser and server, two servers, or another network. Without it, the connection to your website is considered unsecured regarding privacy and data sharing.

Browser problems 

Website visitors receive the “Not Secure” warning from their browsers, so this might be a browser issue. Protocol mismatch, confusing settings, and extensions come to mind. If the browser is the problem, any of these things could be blocking the SSL encryption on your website. 

Server issues 

SSL is not rocket science, but it involves complex computing. So, without going into details, let’s say the “Not Secure” warning sometimes happens because one of the SSL chain certificates between your website and the root SSL  has not been correctly installed on the server.

Poorly configured local system settings 

Though server issues always happen, it’s usually safer to assume that the problem is local. For example, the “Not Secure” SSL error is very often caused by a local firewall. 

Expired SSL certificate 

If you don’t remember paying for an SSL certificate, SiteGround has probably provided a free one for you. Remember that SiteGround’s free SSL certificates are valid for only three months (while paid last for one year). It might be that your SiteGround SSL certificate has expired. 

Six possible solutions to fix the SiteGround not secure message

In short, the best solution for a “Not Secure” warning on your website is a fast one. Luckily, these quick fixes should work in most scenarios, so we suggest trying them right now. 

1. Verify your SSL certificate 

Before anything else, ensure you have an SSL certificate installed on your website. SiteGround users can navigate to Site Tools > Security > SSL Manager

2. Clear browsing data 

For every site that you’re frequently visiting, including your own, your browser collects cache. It helps you browse faster but can also interrupt an SSL protocol. You should clear your browsing data just in case there is an outdated cache causing an insecure connection. 

3. Clear browser SSL state 

Clearing the SSL slate on your browser will ensure that it is not trying to access the website with an expired SSL certificate that’s been stored while it was still active.

4. Disable all browser extensions 

If you’re using Chrome, you can disable all browser extensions by clicking on the three dots and selecting More Tools > Extensions. It’s similar to all other browsers.

5. Reset local system settings 

Check your local system settings to ensure the error is not due to the incorrect date and time setup, security and privacy settings, or your antivirus and firewall.  

6. Get an SSL certificate 

To get a SiteGround SSL certificate, visit Site Tools > Security > SSL Manager. Click Install to get a new one or Renew to keep using the one that’s already there.
