I've used this tool for a long time--but my last log in was months ago. When I logged in this time, the tool asked me to update an authentication code, which I did. Now, when I asked the tool to check all my keywords--every one came back with "N/A" on it. Question: Is the little php script necessary for KT to work now? I'm not sure my server supports php--although I put the script there. We never had to have a php script before.
