Hi Aidan — the icon-poka-twitter etc. are theme icon font classes (not images). You’ll find them in the theme’s icon font files.
Where they are:
In your install: wp-content/themes/pokatheme/assets/ (look for fonts/ + the CSS file that defines icon-poka-* classes)
How to use them:
Add an element (menu item / HTML block / widget) and use something like:
Or if you’re using a menu/social module, it should output them automatically once you set the social URLs.
If you can’t see them on the site, it’s usually because the icon font isn’t loading (cache/minify plugin stripping fonts, mixed-content, or wrong paths after a move). Quick test: temporarily disable minify/caching and hard refresh.
For extra help, email support with your site URL + a screenshot of where you’re trying to add them, and we’ll tell you the exact place/module to use.
(Replying to David: support is still available—email is the fastest way if something is urgent.)
