Home page not invalidated when post is scheduled

[ragdoll]

On my site http://www.fotocomefare.com today I published a scheduled article. The feed was correctly updated but the homepage didn't change, despite I have selected single + front page in the Dynamic Cache Pruning options.
Since I do not update my site often, I set the expiration time to 1 week. However, I need that the homepage be updated as soon as the post is published.
How can I have that?

You're right. And an older one doesn't have any answer yet.
I really like the features of this plugin, but due to the support I think I will switch to another one. Caching is too a critical aspect to be so unsupported.

Well mine stopped working,it now say this in settings Permissions: Please check permissions on /wp-config.php. Quick Cache needs write-access to this file. Permissions need to be 755 or higher.
