I have been trying to leave some blog comments today but without success. Everytime i write a comment and click submit, i get a blank page with the URL as follows http://www.blogdomain.com/wp-comments-post.php I have tried in Firefox, IE8 (with and without compatibility mode) and Google Chrome with no success. I did then tried submitting a comment to a blog without the keywordluv plugin and it worked perfectly fine. I then figured out the reason for it. The problem was that the URL i was putting in the "website" field was an internal page of the website, not the home page. When i changed this to the home page the comment submitted ok. Has anyone else encountered this? Is this a featrue of keywordluv?

I just found this thread after encountering the same problem. In my case it had nothing to do with spam apparently, it simply did not work when I tried to link a specific article. Now that I tried to link to the homepage, it works perfectly.
I have encountered it before, but I found a different way to track its URL. Try attempting to submit a discussion or a comment on the blog you submit and you can get its URL.
