quickstart installation fatal error

Hi,

I have just installed the boutique quickstart and get the following error:

Fatal error: Class 'JControllerLegacy' not found in /var/www/web712/html/websites/hoffmannhaare/components/com_content/content.php on line 15

Any solutions?

Thank you

I am using boutique as Joomla 2.5 version

If this is your first installation please try below.

Can you please download joomla 2.5.6 from joomla.org full package.
Extract its contents.
Delete installation folder and overwrite rest of the folders/files to your website overwriting files.

Make sure there are no file permission issues in your server and that all files uploads or overwritings complete succesfully.

See you around...
