Unable to customize colors

Please could you share a link to your site, MTDRD? I’d be happy to take a closer look for you.

Thanks for sharing the link.

For the Bloglovin border, it looks like your theme is missing the styles to add the dotted border. To fix that, you can add this code to the very bottom of your theme’s stylesheet:

.simple-social-icons ul li.social-bloglovin a {
	border: 1px dotted #ddd !important;
}

For the problem where changing the color scheme doesn’t affect the icons, there are a few things you can check:

1. Be sure to click the “Save” button at the bottom of the widget after changing the color scheme in your widget settings (or the “Save and Publish” button at the top of the screen if you’re editing the widgets via the Customizer).

2. When editing the icon color in your widget settings, check your browser console for JavaScript errors by following the steps at https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors. If you see any errors, feel free to copy and paste them here.

3. You can also try disabling all other plugins temporarily, to rule out plugin conflicts.
