Whenever a user attempted to post a comment to this blog, they would receive the error "It looks like you have already posted this comment".ﾠ A quick search in Google was no help.ﾠ So for anyone else who may receive this error while running a Mango Blog here is what I did to resolve the problem.

First, the error is actually triggered from the component file CommentManager.cfc which sets the variable isDuplicateComment.ﾠ I dug through the file and removed the conditional logic checks for this variable only to discover that the blog still produced the error.

Go to Cache in your Mango Blog admin and press the Reload Configuration button.ﾠ This will allow your changes to take affect.ﾠ Now, for this blog anyway, if you want to leave a comment you can once again.
