In my system I can't understand if the cache is working or not.
I've JoomSEF 4.4.0 with Joomla 2.5.8 and Flang 1.2.0
I've enabled the cache as in image_01,
then I've added a lot of sef urls to the cache,
but the control panel tells me that there are no urls in the cache (see image_02).
How can I check if the cache is working?

Well,
after some research and using the empirical evidence and controls,
I found the solution by myself.
In order to add urls to the cache the general management of the cache must be enabled.
So you can enable it from Site -> Global configuration -> System
Change the values in the area Cache Settings (see the image attached)
At the end I can only say that the manual should be a little more explicit on this topic

Hi,

I'm sorry for the delay. Yes the cache in Joomla must be enabled for JoomSEF's cache to work. Thank you for your suggestion, we'll try to make it clear.
