Error in MTMostVisited. NO hits on MT archives were found in the webserver logs (some webserver logs were found). The plugin determines if it was a MT archive hit by matching the page hits against the $root variable. In your case, it looks for hits that look like http://yoursite.whatever/archives/000001.php . If that URL doesn't look right for your individual archives, then you will either need to change your $root variable or the $filetype variable in the plugin. Note that the $root variable should not have the http/domain thing in front of it, and should not end in a "/". I.e. it should look like /archives or something like that. (It is also possible that you really haven't had any hits on your individual archives. In that case, this plugin is probably not very useful to you.)
