Hi Andrea,
I checked the AutoLoad plugin and compatibility with Rate my Post. So, there are several problems.
1. Rate my Post is designed to allow only one rating widget per post. AutoLoad plugin overrides this and thus prevents Rate my Post from working properly. This could be solved if AutoLoad plugin would allow to call a js function before a new post is loaded (you could remove current widget with jquery) but as I see that’s not the case.
2. Rate my Post depends on wp_localize_script function from where it gets the post id. So, the output of the wp_localize_script function doesn’t change after new post is “auto loaded”. Therefore, even if we call the function to load results it will be always related to the first post and not to “auto loaded” posts.
To be honest I don’t see any quick and easy solution to ensure the compatibility with AutoLoad plugin. Nevertheless, I’ve put this on my list but I’m currently working on AMP, top rated posts widget etc. What you could do though, is to create a function that hides rate my post altogether when new post is loaded.
