Hello Jamie,
Instead of using public_html/jamieharrisonguitar/wp-content/themes/x-child/Fonts/Aver.ttf
, you should be using this URL: https://www.jamieharrisonguitar.com/wp-content/themes/x-child/Fonts/Aver.ttf
.
When using the Font Manager, you still need to assign the Fonts to the Headings or Body and Content in Cornerstone > Theme Options > Typography. Since Aver font is only assigned to the specific text in your Certificate, the code that you added in the Child Theme is the correct one.
By the way, this one is incorrect though:
<p style="text-align: center; font-size: 120px; color: #DAB54F; font-family: "aver"">[usermeta field="first_name"] [usermeta field="last_name"]</p>
The correct one should be:
<p style="text-align: center; font-size: 120px; color: #DAB54F; font-family: "aver">[usermeta field="first_name"] [usermeta field="last_name"]</p>
Please make sure that there are no extra quotations in your code. One thing to take into account is that the resulting certificate is a PDF file. You may need to contact the creators of the Certificate plugin and ask them how to change the Font Family in the certificate since this is a 3rd party plugin (which is beyond the scope of our support). I am sure they would be happy to assist you with that.
Thank you.
