Marketing New products listing stop working

[cactus02]

On the home page of my site (www.secondemain.ca) I had « Best Sellers » (still there) and « New products listing » activated.
Returning from vacation, I noticed that « New products listing » was not displayed. I try to reactivate the listing without success. Some of the features are not available : Number of products, Day, etc...
If I manually add products, they vanished on reloading the program.
Any suggestions ?
Thank you !

O.k., it's now working !
All new products inserted in the site where out of the date range !
The last products that I add to my site don't have the « right date » !
In the « Product » table, the last update date is 2014/10/07 but the « sCreate » date was 2014/08/13 !
I change de « sCreate » date for 2014/10/07 and the Marketing list is working !
What change the « sCreate » date ?
