Please notice that from November 2023 I have tried to upgrade from joomla 3 to 4. I rebuild the website from scratch. I'm spending many hours editing things. I don't like to lose time for beginner pieces of advice to uninstall and re-install it.
I like page builder and helps my website to become much better but you have huge problems still! Before 2 years (when I started using it) the interface was more unstable. Now things are better. But they are not perfect. And be sure that you don't want me start reporting the errors...
Even like this the icons are ok. I'm searching the https://fontawesome.com/v5/search?o=r&m=free or I ask chat gpt opinion.
PLEASE do not do something that can break down my website. I was working for 8 hours yesterday fixing problems. Even if I have a back up you delay me approximately an hour by re-install the website online.
