Resolved Ssl certificate says unencrypted parts

[python]

I am using let's encrypt and it works fine but the main page of the site tells me that parts of the web page are not safe as images I get the warning in yellow, this is normal is my website error or is the certificate , I need all my site to be encrypted.

I am using the 17.5.3 version of plesk onyx

Your website is doing that.
It is showing content with plain http as well and that's a big nono.
Modern browsers will warn users if they are connected to https-sites with http content (mixed content).

If it's a WordPress site you can easily fix it with the plugin "really simple ssl".
You should search the internet for "mixed content" and try to understand what is being explained.
