Errors After Upgrading WordPress

I would have replied to one of the existing topics, but it appears they are closed. Just hoping this can help someone else out.

I believe the issue is that the proper file no longer gets included in code when the admin ajax request is happening. I was able to patch it and have not yet noticed any side effects.

In social-icons.php Line 139-141 – remove the if statement, keep the include_once.

So this:

if ( $this->is_request( 'admin' ) ) {
    include_once( SI_ABSPATH . 'includes/admin/class-si-admin.php' );
}

Just becomes this:
include_once( SI_ABSPATH . 'includes/admin/class-si-admin.php' );
