As i checked your plugin have not any filter for “wp_get_attachment_image_src” function and out theme is using it to get thumbnail details. Please add following code into into your plugin to make it compatible with our themes ( and third-party themes and plugins).

`add_filter( ‘wp_get_attachment_image_src’, ‘fifu_replace_attachment_image_src’, 10, 2 );

if ( ! function_exists( ‘fifu_replace_attachment_image_src’ ) ) {
/**
* Replaced attachment src with external thumbnail URL
*
* @hooked wp_get_attachment_image_src
*
* @param $image
* @param $attachment_id
*
* @return array
*/
function fifu_replace_attachment_image_src( $image, $attachment_id ) {

if ( $attachment_id == get_post_thumbnail_id( get_the_ID() ) ) {

$src = get_post_meta( get_the_ID(), ‘fifu_image_url’, TRUE );

if ( $src ) {
return array(
$src,
0,
0,
FALSE
);
}
}

return $image;
}
}
`

Thanks for your efforts and good works.
