Cleared the Cache in BO now BO is White Screen

[mallrat]

Hi there

In BO -> advanced parameters -> performance I clicked the clear cache button. Now the BO login is just showing a white page. The front of the site is all running OK.

I manually switched on the debug mode and when I try and get to the back office login page it says...

RuntimeException in PhpDumper.php line 1403: Cannot dump definition because of invalid class name (NULL)

Nothing has been added or removed to the site and it was working perfectly before I clicked the clear cache button.

I hope someone can help.

Thanks.
