I had a trouble with the reading tools. When you did click over "about the autor" or "how to cite item" i obtained the error pop-up page "404 page not found". In order to solve that problem I followed the next steps.
(using the latest OJS version 2.1.1)
1. Go to http://pkp.sfu.ca/cvs/cvsweb.cgi/ojs2/p ... er.inc.php
and download the latest version of RTHandler.inc.php, at the moment 1.40
2. Open your ftp client, and search that folder : pages/rt
3. Upload the new RTHandler.inc.php file (overwrite the older version)
4. E voilÃ ! it works!
