Great thanks! I will follow your good advice :)

And this is what I currently have in my child functions file (below) so just need to know where to add the fallback code and how? Thanks!

<?php

add_theme_support(‘avia_template_builder_custom_css’);

add_theme_support(‘avia_disable_dummy_import’);

function cc_mime_types($mimes) {
$mimes[‘svg’] = ‘image/svg+xml’;
return $mimes;
}
add_filter(‘upload_mimes’, ‘cc_mime_types’);
