title: Magento - 404 only in edit/section/dev/
body: <p>I'm having some trouble entering my Configuration>Advanced>Developer section to enable the profiler ex. when this www.sitename.com/index.php/system_config/edit/section/dev/ URL is loaded, I get a 404 error. I've checked through all my logs, no clue on why this is happening? </p>
  
  <p>How could I trace the source of the problem? - no clues in logs. And it's on a live site, it's been a long time since I've last used this part of Magento, so I don't know if anything was installed or changed that could have provoked this, sadly. </p>
