I'm the developer of the 'AppStore' Plug-in. And I addet a 'dynamic' Widget in Version 2.0.
The widget uses a RSS-Feed and now i would like to cache this feed. I'm trying to update a setting in the widget() function with
$instance['feedUpdateTime'] = time();
but this does not work, because I think, that this is just the active intance. How can I update this setting?
Do I have to use the update($new_instance, $old_instance) function? How do I call this?
