Squarespace Site Says Not Secure (SSL Error)
Quick answer
A 'Not Secure' warning on Squarespace is usually SSL set wrong, a certificate still being issued, or mixed content from http:// embeds. Set SSL to Secure (Preferred) and replace http:// links.
Most likely fix: Turn SSL on
How to fix it
Try these in order — the most common fix is first.
1. Turn SSL on
- Open Settings > Advanced > SSL
- Set the security preference to Secure (Preferred)
