I checked my site with validator.w3.org and there was an error: "XML Parsing Error: Extra content at the end of the document . </html>_" I noticed that at the end of webpage that is generated by akelos, there are 3 illegal characters that should not be there:  (EF BB BF). I checked my page.tpl layout and it doesn't have this characters at the end of file. I copied page.tpl to other controller's layout and page that was generated in other controller was correct. Why is this error present?

Illegal characters were present because in app/locales/page/ there was files that had EF BB BF at the beginning.
