When moving sites, from time-to-time, the divi theme loses some settings, and the arrors in the primary menu, and arrors in images sliders, etc show numbers instead.
To solve this we must add some code to the header to pre-load the fonts before the page is loaded.
To do this, first go into the Divi settings, click “Integration” tab. Paste this into the header box.
<!– Preloading font to fix menu icons –>
<link rel=”preload” href=”/wp-content/themes/Divi/core/admin/fonts/modules.ttf” as=”font” type=”font/ttf” crossorigin=”anonymous”>
<!– Preloading font to fix menu icons – end –>
Save changes.
