How to show Related Posts after the_excerpt in wordpress blog

I am using the wordpress plugin that created "SEO Auto Links & Related Posts" by Purwedi Kurniawan. I realized that this plugin will show the related post only in single post if function the_content() was called. My single post doesn't show the_content instead of only the_excerpt().

I made some modification for this plugin to show related post not only when the_content() is called but the_excerpt as well.

Here are the some modification that i do :

1. Edit the plugin "SEO Auto Links & Related Posts" --> seo-alrp.php
