Recent Post Slider tidak muncul di Front Page

I used WP Responsive Recent Post Slider plugin in my wordpress, after I put code [recent_post_slider] as text widget for Home/Front page, the slider did not shown anything except the code [recent_post_slider] itself. But, when I put the code as a post content, and then I view the post, the slider is visible correctly.

Theme:
Directory Starter used with Plugin GeoDirectory

Problem:
Kode [recent_post_slider] di text widget tidak muncul sebagai post slider di Front Page template, namun post_slider bisa tampil di template artikel/post

Solusi:

Mengganti kode [recent_post_slider] di widget text dengan cara menambahkan

echo do_shortcode('[recent_post_slider]');

di File: plugins\geodirectory\geodirectory_template_actions.php

function geodir_action_geodir_sidebar_home_top()

setelah baris

dynamic_sidebar('geodir_home_top');
