is more time dont use setup now I try to install a clean version of forum on other machine to try reconfigure all but just have 1st problem when setup finish cant see block for calendar .... and no menu in content managmente zone .... possible?

Hello,

If you run the Setup Wizard and don't choose the calendar addon, it will be uninstalled.
You can install it from Admin Zone > Structure > Addons.
You then will need to add the block manually.

I search but dont find … I find a Calendar from 6am but no more appen if install

PS

NOthing Don't know HOW but I install

It should already be in the list directly at Admin Zone > Structure > Addons as it is a bundled addon.
