I am doing the changes in the admin interface of staging only and not in local. what i am trying to say is that its not reflecting in staging environment. please help
Can you let me know what settings are not reflected so we can investigate ? Cache settings or some other settings ? If we are talking about the Cache settings then you need be know that cache settings per WebPart are used for database access caching purposes so you will still have a page lifecycle and you will have the request to web server but you will not have request to db server.
I have posted a question regarding your first and second post:
did you try to sync the discussion user control markup with the latest version of MonoX ?
We did some work around that in 4.7 or 4.8 if I can recall correctly.
