Math Comment Moderation Plugin

Hi,

 

I just enabled the math comment moderation plug-in, but it doesn̵7;t really work.  Even if I enter the correct answer, the comment is not added.

 

The Tomcat log looks like this:

 

Mar 15 00:39:10 INFO  [http-8082-Processor19] comment.MathCommentAuthenticationPlugin - Failed math comment authentication check.

Mar 15 00:39:10 INFO  [http-8082-Processor19] comment.CommentPlugin - Comment meta-data contained destroy key. Comment was not saved

 

What’;s wrong here?
