I have configurated the blocks from system administration menu. But... suddenly is missing the block related at "recent comment".
When browse, from module --> system admin--> module, and find for description block..."recent comment" there is not anymore!
Only chenge that I could have done, it is in the change to exclude him from the visualization of some pages. (ex. in faqs pages).
I have also excluded other blocks for the visualization for different user, but they is visible however, while "recent comments" has disappeared !
How is possible this?
How can I make up for?

Kind Regards,
Valeria

At the top of the blocks administration page there is the line called "Show blocks visible in ..". Normally there is selected "Top Page". You can select other modules there. Choose the one you made this block visible for and i'm sure it will be shown.

Ok, you are right!!!
I have amiss set this, only for the page... contact!!!
I'm sorry!
But thanks a lot, for support.

Kind Regards,
Valeria
