Error with using browser-sync with Gulp in localhost

Hi, in my workflow I use browser-sync with Gulp, normally the permalinks are like this:

http://localhost:3000/mywebsite/store-item/

But when I use the Ajax Load More plugin, the permalinks change to:

http://localhost/mywebsite/store-item/

Here my shortcode:
<?php echo do_shortcode(‘[ajax_load_more repeater=”template_1″ post_type=”mic_store” posts_per_page=”10″ transition_speed=”500″ scroll=”true” transition=”fade” transition_container=”false” button_label=”Ver Más” button_loading_label=”Cargando…”]’); ?>

It seems that exist a conflict with the plugin and browser-sync.

Thanks for any advice!
