After moving a site to HTTPS, many WordPress databases still contain <code>http://</code> references to your own domain in posts, meta, and options. That can cause mixed content warnings and broken images in the browser.
Solaxes HTTPS Migration Repair helps administrators:
<ul>
<li>Scan selected WordPress database tables for HTTP URLs on your own domain only</li>
<li>Target content types: images, pages, posts, CSS, JavaScript, and other references</li>
<li>Live preview (frontend only): rewrite HTTP to HTTPS in page output without database changes</li>
<li>Review summarized scan results by content type</li>
<li>Export detailed findings as CSV or JSON</li>
<li>Run a dry run before applying changes</li>
<li>Apply serialized-safe HTTP to HTTPS repairs in batches</li>
</ul>
This plugin helps detect and repair common HTTP references stored in the database. It does not guarantee that every mixed content issue on a site will be resolved. It does not rewrite third-party <code>http://</code> links, and it does not modify theme or plugin files on disk. Always take a full database backup before applying permanent changes.

It easily solves the problem of mixed unsafe content.
Once a web page has its contents, such as CSS, JavaScript or graphics loads unencrypted, the browser reports the whole website as unsafe.
This message will appear with this or similar texts “Connection is not secure” and “Parts of this page are not secure. This can e.g. be graphics. “.
Now you can check and correct all posts, comments, plugins and the theme …
Or you simply install “SSL Fixit”. 
Finished. There is nothing to configure.
The plugin simply replaces all http: // in the output with https: //.
However, if you still need unencrypted links, you can not use this plugin. 
But that should / should be there in the meantime only in exceptional cases.
