I Install Joomla 1.5.9  and VirtueMart 1.1.3, but when I tried to install VirtueMart component, I got an error:

Update Log
Critical Error:

Some Core Files for VirtueMart are missing, but they are required for installing and running VirtueMart. If you see this message it’s recommended to attempt the Manual Installation of VirtueMart!

Click here to return to Joomla!

thankfully, I got the solution from VirtueMart Forum :

Deleted the files in:
/yoursite/administrator/components/com_virtuemart   and 
/yoursite/components/com_virtuemart
 run Install/uninstall from Joomla(to remove virtuemart from components listing- you will get an error here:)- it’s OK)
Installed the pakage again
Got to the point where it says “The first step of the installation was successful”
NOW DON’T CLICK on install sample data or go directly to shop YET.
Chmod the directories:(use joomlaXplorer or FTP)
/yoursite/administrator/components/com_virtuemart   and 
/yoursite/components/com_virtuemart   to 777
Now click on ” go directly to shop” or ” install sample data”
(don’t forget to chmod them back to 755 after install)

There is an easy way to upgrade your wordpress CMS, use “Wordpress Automatic Upgrade“ 

” Wordpress Automatic Upgrade allows a user to automatically upgrade the wordpress installation to the latest one provided by wordpress.org using the 5 steps provided in the wordpress upgrade instructions. Go to Wordpress Automatic Upgrade to upgrade your installation Thanks to Ronald Huereca for making the plugin run in automatic mode. By Keith Dsouza.”

but when I started to use this plugin, the trouble was started: “Your server is running in safe mode. WPAU cannot continue in safe mode. Please ask your system administrator to change the setting to disble running in safe mode“

then I make file php.ini with script-code  ”safe_mode = off” in it, and upload it at public_html, then I checked safe_mode status at phpinfo, safe_mode status was off, but I didn’t know why the automatic wordpress upgrade didn’t work with the same warning.

Finally I decided to upgrade my wordpress CMS manually, I download the newest wordpress 2.7, exctract it and replace all file in server except:

1. wp-content folder and all file in it
2. wp-config.php

then start admin page with a little upgrade on the database (just by clicking  the button) and upgrade was done.
