Hi,
1) what kind of customization you've done ?
2) white/ blank screen in whole admin or in selected component / module ?

Hmm?

Hi,
not really much, screen gone blank in whole admin.
Now it is sorted ... looks like mod_vmmenu requests access to some joomla api.
VM is a mess

Thanks anyway

I fully agree - it can be used only for crazy ones, or those who have lots of time to searching answers of forums.
Most of my friends do not use it anymore since last year.
