First thanks so much for getting back to me so soon.

Sorry I wasn't clearer here's what happened:
PROBLEM:
# I was using the SilverStripe interface, the site tree. We have a top level page which has other sub-pages underneath it
# I right clicked the page and used Duplicate page and children [That worked fine]
#I then changed the name of the page [That worked fine]
# I then went to move the page and it's children by dragging and dropping them
# The interface timed out
# Now I can't login to admin
# I can't see the site
# Here's the error's i'm getting http://www.gcd.ie/newdemosite/
TRIED:
I tried to clear the cache using the following
# http://mysite/?flush=1
# http://mysite/?flush=all
# http://mysite/dev/buildcache/?flush=1
# http://mysite/dev/buildcache/?flush=all

None of these seem to be working

I didn't move any of the back-end template files

Really Bizarre

Thanks in advance for your help

Hi Martimiz

Yes I tried that but it fixed only part of the problem you were right the name was spelt wrong now I have eliminated/deleted both files PostgraduateCoursePage.ss and PostgraduateCoursePage.php done a dev build and get this error but I can now see the front end of the site still can't get into admin area.

Thanks Gemma
