I've installed an Wordpress from Debian Wheezy package system and the plugins folder appears to be broken.

As stated in the error log files of Apache2:

[error] File does not exist: /var/lib/wordpress/wp-content/plugins/var

The plugins are looking for an URL based on the full path, and not on the relative path. I can "temporary fix" the problem making a symbolic link to /var on the plugins folder, but I know that this is wrong and dirty.

I don't know where to start debugging this. So any help is welcome.

Additional information: /etc/wordpress/htaccess

# Multisites generated htaccess
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Apache2 Configuration File:

<VirtualHost *:80>
Alias /wp-content /var/lib/wordpress/wp-content
DocumentRoot /usr/share/wordpress

ServerAdmin [email protected]

<Directory /usr/share/wordpress>

Thanks in advance,
