After updating to version 6.9, some things no longer work. Seems all is working properly here. Can you try clearing the browser cache and then reloading couple of times while holding down shift. That’s the “magic” fix in many of the cases 🙂 I tried that, but it doesn’t help me. It looks like it only happens in Firefox 115.31.0esr. only happens in Firefox 115.31.0esr In this case it was probably broken there? Works fine in the latest release of Firefox and all other popular browsers. These icons come from a custom font. Maybe have a look in the browser tools – network to see if custom fonts are being loaded, and if not perhaps open an issue for it. It’s probably a WordPress bug. https://github.com/WordPress/wordpress-develop/pull/10636 I’m having the same problem here, in addition the checkboxes icons are not working as well probably a WordPress bug Right, WP 6.9 introduced a CSS bug for old browsers. Imho better to update your browser, but in any case it will be fixed in 6.9.1. This reply was modified 4 months, 3 weeks ago by Andrew Ozz .
