I have the comment plugin installed. But of late, there has been a spate of spam comments on one particular blog post. In just two weeks, there has been over 150 spam comments on that post. Whenever I tried clicking on the 'close comment' there is always a problem with the page returning a 'oops' error. What can I do? Is there a way of removing those spam comments?

Which plugin do you mean?

Cant find a comment plugin ...

By the way - some gpEasy plugins can use the reCaptcha service, you can insert your login data in admin section.
