Since Elementor v2.6.0, Font Awesome icon library was updated to v5.
The idea behind updating Font Awesome to v5 is giving Elementor users the ability to choose between over 1500+ icons.
In order to update Font Awesome version, you should have received the update notification message
After hitting the Update button, you will be redirected to your dashboard -> Elementor > Tools page. Here you will find the Migrate to Font Awesome 5 button
When you click Migrate to Font Awesome 5 button, you’ll be prompted with the last popup reminding you this action is irreversible and reverting back to older version will not undo the migration.
For further reading about Font Awesome 5 migration, please check Elementor Font Awesome 5 Migration doc article.
In some cases, you may not be able to see Font Awesome icons in Premium Add-ons for Elementor widgets. So, here’s how you can resolve that:
This usually happens when Font Awesome 4 icons are used in the widget, it can be resolved by navigating to your dashboard -> Elementor -> Settings -> Advanced tab, then enable “Load Font Awesome 4 support” option.
Note: If you didn’t update to FA5, Premium Addons for Elementor widgets that use FA4 icons will still continue to work, but you will not be able to change the icons.
