Hello,
Please add this code to the functions.php of the child theme:

add_filter( 'basel_intagram_user_ajax_load', '__return_true' );

Next, find the file

basel\inc\shortcodes\shortcodes.php

Find this line:

if ( is_wp_error( $media_array ) && $media_array->get_error_code() === 'invalid_response_429' ) {

and replace with this line:

if ( is_wp_error( $media_array ) && ( $media_array->get_error_code() === 'invalid_response_429' || apply_filters( 'basel_intagram_user_ajax_load', false ) ) ) {

Best Regards
