[!CacheAccelerator? &snippetToCache=`Ditto` &cacheId=`news` &display=`20` !]
Try logout from manager or open in another browser.
When I have a cached page & uncached Cache Accelerator snippet call I get :
MySQL: 0.0883 s, 264 request(s), PHP: 0.1329 s, total: 0.2212 s, retrieved from cache
In my folder assets/plugins/cacheaccelerator/cache/ I have only one file named application with no data in it.
Is that correct?
I will try with pagination later.

If so, then you should set all ditto calls through CacheAccelerator, but i don’t know what results will be.Tried the second level Ditto call inside the Ditto tpl with CacheAccelerator, but didn’t get the expected results.
Have you set different cacheId on all CacheAccelerator calls?
