Non-secure website despite Active SSL certification

Hello! 
I am new to Squarespace and a novice to site design and coding. Recently, I launched a website at apexeyenc.com, but there is a unsecure notification when typing in that domain name. Only when the entire website address is typed (https://www.apexeyenc.com) are you able to browse through the site. The SSL certificate is active, and I have attempted to run the site through multiple SSL checks and passed (doesn't appear to be a mixed content issue). 

Any help or suggestion is much appreciated! Thank you so much.

It is working fine for me. I suspect you are seeing the error because of your cache. If you clear the cache or wait for it to expire, it should work fine for you too. 

I cleared my cache and that seemed to help. However, now my ISP (Spectrum) is claiming that there is unsafe content. Any suggestions?

This is for the same reason (your ISP also caches the content that you view) and should resolve itself within a couple of days.
