Admin menu missing?

Hi,

Nofollow Case by Case starts working right after activation.
There is no need to configure anything.

You might want to have a look into the source code of your comments to see if nofollow has gone after activating the plugin. You can also try a modified link (replace nofollow like this: one_comment_authorlink/dontfollow) to check if the link still works with this modification. If it works, your output is filtered by the plugin. This means the plugin works.

Best regards
Oliver

You are welcome!
