aymeric75 on "plugins update..."

Hi everyone,

My site was blocked because of a hacking problem. I ask the sever (OVH) and they told me that i should update all the plugins.

The problem is that when i go on my admin session, if i click on "plugin update" i have the following error message and i don't know how to ix it:

Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 9: parser error : Specification mandate value for attribute noshade in /home/lceekgnu/www/wp-content/themes/extranews/functions/update_notifier.php on line 97
