HI

Upgraded recently from 3.8.11 to 3.9 and now the backend (administrator) is blank.

After enabling public
$error_reporting = 'development';
in
configuration.php
Error is:
Fatal error: Class 'JToolbarHelper' not found in /home/appcedar/public_html/administrator/components/com_cpanel/views/cpanel/view.html.php on line 36
'

Any ideas how to correct this?
n/b: The upgrade hung for a while and ultimately failed to complete. I am so sad because, for the first time, I did not first backup.

Thanks, Chiemeka

Solved the Problem.
I went through all the folders by date and replaced only the ones that were updated at the time (actually only one). And then I could log in again.
Have updated and all is well.
