limit dosen’t work after last upload

Hello,
after last upload when I change the limit in the shortcode the plugin dosen’t work. The website doesn’t display nothing.
es.
[wp_my_instagram hashtag=”myhashtagname” limit=”8″ layout=”” size=”large” link=””]

The plugin works goods if I use the shortcode without the limit but It shows all the hashtags
es.
[wp_my_instagram hashtag=”myhashtagname” limit=”” layout=”” size=”large” link=””]

Can you help me?
Thank you
