Icons are not shown properly

The icons are not displayed as it should be. I used the fusion builder to create the icons. Now, only grey circle is shown. After some research I found this solution to the problem, https://theme-fusion.com/knowledgebase/are-your-font-awesome-icons-or-custom-fonts-not-showing-up/ . I applied this and still the icons are not displayed properly. ( see website http://vluchtwegaanduidingen.nl/noodverlichting/

Hopefully someone is able to help me to solve this.
