Did the error occur again, or the issue has been resolved by itself? That's a pretty strange behavior, so please inform me if the error reoccurs.
For news items, do you want to set the PublicationDate of already created items or you want to set it while you're importing the items from your old site. If it's the first case, you can easily do that by adding a custom field of type DateTime to the News module. Just follow the instructions below:
1. Add a custom field to the News module of type DateTime and name it ArticleDate
(or whatever name suits your design purposes)
2.In this new field that will appear at the bottom of each News item you can set the desired Publication date.
3. Once you've set the field for all items, you can run the sample code below which will set the PublicationDate to the value in ArticleDate on all news items.
var newsAll = App.WorkWith()
.Where(nI => nI.Status == ContentLifecycleStatus.Live)
var val = nI.GetValue(
var ss = DateTime.Parse(val);
nI.PublicationDate = ss;
If you want to implement different functionality, please provide me with some more detailed information, so that I can advise you further.
