Statistics don't display

You read the documentation?

Settings
Place Editor
Statistics

Advertising Request Addon

Yes I read the documentation
I have set places and linked each ads to accurate places
In the settings I have allowed the plugin to collect and to store statistical data but I still have no impression and no clicks statistics

What view mode you select “All” or “For Sale”?

I tried both of them.
May be a conflict with another plugin ?

Maybe…

Try PHP and Javascript output mode…

I am using Caching Compatible output mode (Javascript) as I am using W3 Total Cache
I will try the php mode, is there any “danger” if I am using W3 total cache ?
Thank you for you reactivity and sorry to bother you

Better to use Javascript mode… Try clear cache of W3…
