Hello @Jeroen:
Since you are using elementor, our theme includes Font Awesome version 6.7.2, which may not be fully supported by Elementor at this time. As a result, some icons might not display correctly when using Elementor widgets.
To resolve this issue, you can add the following CSS to your site: Go to Dashboard > Appearance > Customizer > Additional CSS.
Paste the provided CSS code into the Additional CSS field.
.font-awesome:before,
#feature-slider .cycle-prev:before,
.sidr .dropdown-toggle:after,
#feature-slider .cycle-next:before,
#content-prev:before,
#content-next:before,
.posted-on a:before,
.byline a:before,
.cat-links span+a:before,
.tags-links span+a:before,
.comments-link a:before,
#header-toggle:before,
.edit-link a:before,
.sidr .menu-item-has-children a:after,
.sidr .page_item_has_children a:after {
font-family: "FontAwesome" !important;
}
This should help ensure the icons display properly.
Sincerely,
Minal
