[SOLVED] Upgrade V1 - V1.3 Admin login blank screen

[airbag]

Hello, upgrading V1 to V 1.3

* New set of 1.3 files with no changes
* Insert existing settings.inc.php file into config directory
* Run update on the installer (no SQL errors showing and looks like success)
* Hit admin page which asks you to rename directory.

When loading the new admin URL all that is showing is a blank page. The frontoffice displays fine.

I have tried this 3 times now.

Anyone any ideas? (remember this is a brand new 1.3 fileset hooked up to the existing V1 database which has had the installer run over it with no errors).

Thanks.

After another test upgrade the problem was resolved.

It was permissions on the admin folder after the rename of it.
