The message says that enewsletter.publication_date is nil. Check the database to make sure that all instances have a valid date for this field.  you should add a validation to the model to prevent creating a row with a nil value.

Hello, I'm a newbie. I need help resolving this issue. I recently added a pdf to the newsletter admin section of the website and now I can no longer view page 2 of the list of pdf's. Nor can I login to see the newsletters as a student. I'm using Ruby 1.9.3, Rails 3.2.1.

Here's the information from the log file.

ActionView::Template::Error (undefined method `strftime' for nil:NilClass):
