## Code

```php
$wpide_https_fix = function ( $content ) {
    if ( ! is_ssl() && 'https' !== wp_parse_url( home_url(), PHP_URL_SCHEME ) ) {
        return $content;
    }
    $host = wp_parse_url( home_url(), PHP_URL_HOST );
    if ( ! $host || false === stripos( $content, 'http://' . $host ) && false === stripos( $content, 'http://www.' . $host ) ) {
        return $content;
    }
    return preg_replace( '#http://((?:www\.)?' . preg_quote( preg_replace( '/^www\./', '', $host ), '#' ) . ')(?=[/"\'\s:]|$)#i', 'https://$1', $content );
};

add_filter( 'the_content', $wpide_https_fix, 99 );
add_filter( 'widget_text_content', $wpide_https_fix, 99 );
add_filter( 'widget_block_content', $wpide_https_fix, 99 );
```

## Notes

Only your own domain is changed; a database search and replace is still the permanent fix.
