- Safe path error - shop don't start - white page

[amedeo]

I need a little help.
I installed VM 2 and all ok.
Versione PHP: 5.3.8   - Server Web: Apache/2 - Joomla! 1.5.26 Stable
I have a problem with file configuration.
if I go into the store or preview there is always a blank page
On menu Templates there is a Safe path. When i make Save i see this alert:
Warning, the Safe Path is empty, for safety reasons it is very important to create a folder in a path not accessible by an URL, create also a folder invoices in it to store your sensible data secure. Our suggested path is for your system /home/ucxjxmze/domains/stickersmurali.joomlahost.it/vmfiles
I do not know if you need to create a folder and how to use the url. If I use the same address as the view I get the same warning. Can you help me?. I'm not very handy but I try to commit.  Tanks a lot in advance

For a blank page there could be a different issue. See http://forum.virtuemart.net/index.php?topic=62675.0

That is a Joomla generated error coming from the Joomla cache - Joomla 1.5 is reported to have some issues when on PHP 5.3.8

You should manually create the safe path directory, but maybe also be using Joomla 2.5 instead of Joomla 1.5
