Hello
We have just updated the Ensley template with a number of fixes including a fix to hopefully resolve any related issues regarding fonts. For details on updating your template may I suggest the following article..

If the issue persists after updating, may I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.
I should also mention that if using the old Font Awesome 4 syntax, you must add the
fa class to the font element. In Joomla 3 this was not needed but as Joomla 4 is loading Font Awesome 5, it will be now required.
<i class="fa fa-check-square"></i>
