first roll changes : follow step change admin url

1) change path in app/etc/local.xml

<admin>   <routers>     <adminhtml>       <args>         <frontname><![cdata[administration]]></frontname>       </args>     </adminhtml>   </routers> </admin> 

2) remove cache remove cache folder rm -rf var/cache/*

then check it.
