Thank you for responding Tom. I just ran the svn update and attempted to reinstall the update. I got the same blank page for schema update and error message in the apache error log. So no luck here.

Right now we are unable to deploy new client machines. So after cloning this vm, I’m going to roll back the image to before the attempted upgrade. I did find the issue which was the trigger that caused me to attempt the upgrade. After I get the vm restored and fix the other issue, we’re all good.

If you want me to test anything additional I’ll keep the broken vm for a while.

Bump

Any idea on how we can solve this issue? We are unable to login or even interface with the software from the FOG PXE menus since they interact with PHP. We get this error in the apache error log if we try to interact with the web interface or via the PXE menus:

PHP Fatal error: Call to a member function get() on boolean in /var/www/html/fog/lib/plugins/accesscontrol/hooks/RemoveUpload.hook.php on line 28

Sorry I was short on the details.
Centos 6.7
While I don’t have the SVN number I upgraded from, the fog login console graphic had 4388 in the graphic. I can estimate (pretty close) the last svn update was done on 11-Aug-15

I just updated to the latest svn version 3981 too, in an attempt to resolve a fog pxe boot issue. And I’m also getting the same blank screen when attempting to update the schema.

Looking in the http error log I see the following error:
PHP Fatal error: Call to a member function get() on boolean in /var/www/html/fog/lib/plugins/accesscontrol/hooks/RemoveUpload.hook.php on line 28
