E_ERROR: avia_font_manager class not found (class-social-media-icons.php)v7.1.3

Hello Enfold Support Team,
I am experiencing a recurring fatal error on a live website (https://www.drisabelbalza.com) that triggers WordPress “Your Site is Experiencing a Technical Issue” emails repeatedly.

Environment:
WordPress version: 6.8.3
Parent theme: Enfold 7.1.3
Active theme: Enfold Child (version 7.1.3)
Current plugin: (version )
PHP version: 7.4.33

Error Details:
An error of type E_ERROR was caused in line 223 of the file /home/drisabel/public_html/wp-content/themes/enfold/includes/classes/class-social-media-icons.php. Error message: Uncaught Error: Class ‘avia_font_manager’ not found in /home/drisabel/public_html/wp-content/themes/enfold/includes/classes/class-social-media-icons.php:223

Stack trace:
#0 /home/drisabel/public_html/wp-content/themes/enfold/includes/classes/class-social-media-icons.php(259): avia_social_media_icons->build_icon(Array)

#6 /home/drisabel/public_html/wp-content/themes/enfold/header.php(275): get_template_part(‘includes/helper’, ‘main-menu’)

What I’ve already tried:
1- Purchased and installed a fresh, original Enfold 7.1.3 download
2- Verified that only one Enfold parent theme exists in /themes/enfold
3- Confirmed child theme only contains custom files (no class overrides). It exists in /themes/enfold-child
4- Switched PHP versions (8.1 → 7.4.33)
5- Cleared cache and re-uploaded theme via FTP
Despite this, the error has persisted since August 27, 2025, and continues to send automated WordPress admin emails.

Questions:
It appears that avia_font_manager is not being loaded before class-social-media-icons.php is called. Could you please advise:
– Which file should load avia_font_manager in Enfold 7.1.3? May I need a code snippet somewhere?
– Whether this indicates a corrupted load order or a missing include
– If this is a known issue with WordPress 6.8.3
– I had a long stack trace list when I switched from PHP 7.4.33 to PHP 8.1, and it was worse in PHP 8.3, which is why I downgraded to PHP 7.4.33, where the list is shorter.

Thank you for your help.
Best regards,
Claudia.
