How to link plugin correctly to multiple posts on homepage?

Hello,

I purchased the 'Pay With A Like' plugin and installed it on my site Buymyidea.com.

It works on individual post pages, but I want the plugin to also work on multiple posts displayed on the homepage and link to the individual post's URL. When I try it now, the plugin uses the homepage URL on each post displayed there.

How can I fix this? I could not find an option in the WordPress backend...

Many thanks,
Rene

Ps. If you check the site now I inserted the 'Read More' tag for the time being. But don't want to have to use this tag in the future.
