Images don’t load erratically

I see multiple messages about images and some script blocked in Chrome with (blocked:mixed-content) reason. Which basically means it doesn’t like unsecure http resources in secure https site.

WordPress doesn’t handle this particularly well. It is designed to use absolute URLs and they tend to end up hardcoded in content and such.

You would have to:

• redirect everything to secure version on web server level (unless you need both for some reason);
• update WP data in database for secure links (with suitable search/replace tool);
• update any custom code to use or generate proper versions of links to assets properly.
