Recently i need to migrate a Drupal 6 website to a hosting. Everything seems work fine but the Admin module fails to work. The following error is shown in Firebug console.

• $.cookie is not a function

After checking the module issue, it is found that the error was caused by the mod_security setting. But i have no permission to edit Apache setting in the new hosting.
Luckily the following patch by pdrake works
Download jqcookie by pdrake

The problem is resolved after enabling the jqcookie module.

Done =)
